I'm simply trying to sum a column in a query. The query is also used for a list control on that same form, and I'm displaying the column I want to sum, so I know that
Ms Access #error In Sum Field
the query is working and correctly finding the values. But the sum yields "#error." Here's what I've done so far to try to sort the issue: - I've confirmed that the text control doesn't have a name that collides with anything else - I've used "nz": the express is sum(nz([field name])) - I've let the expression builder fill in the fields to minimize the chance of typos; I've re-entered this many many times now, to no avail. - The underlying table field size is "single"; I've looked at the query and control, and there doesn't seem to be any related property that would clash with that - Just to make sure the null value wasn't an issue (despite using "nz"), I put a hard value in for debug purposes; still #error - I created a completely separate dummy table that has nothing to do with anything in the actual application. I had simple integer rows with no null values. I pointed the control at that instead; still #error. - I created a separate query to sum the column. The query itself works and yields a v
Unlike fields in a table, there is no way to specify the data type for calculated fields. If your data sorts incorrectly, or the wrong records are returned, Access is probably treating your calculated numeric or date field access #error in textbox as text. Typecast calculated fields to avoid these errors. Calculated fields are widely used ms access if error in normalized databases, and this problem is ubiquitous. There are postings every day in the newsgroups that trace back to this issue.

(If this is a new area for you, see calculated fields.) In Queries This example calculates when payment is due - 30 days from the order date, or today if the order date is blank: SELECT https://social.msdn.microsoft.com/Forums/office/en-US/0d7a8c95-fed9-469e-a610-2762e1da187e/error-issue-with-simple-sum-calculated-field?forum=accessdev OrderID, Nz(DateAdd("d",30,[OrderDate]),Date()) AS PaymentDue FROM Orders; Test it by opening the Northwind sample database, creating a new query, and pasting the statement into SQL View (View menu). You will notice that Access left-aligns the PaymentDue field. That is a visual clue that it understands the calculated field as text. Sort or filter on this field, and your results will be wrong. To specify the data type of a calculated field, wrap the http://allenbrowne.com/ser-45.html calculation in CDate(), CLng(), CDbl(), CCur(), etc.: SELECT OrderID, CDate(Nz(DateAdd("d",30,[OrderDate]),Date())) AS PaymentDue FROM Orders; These conversion functions cannot handle Null. Use Nz() inside the conversion. Hint: Use CVDate(). While this function is a vestige from Access Basic, it is incredibly useful for calculated date fields. It allows you to output Nulls and still have Access recognise the data type correctly. In Forms and Reports For calculated controls on a form or report, all you need do is set the Format property of the control. In general, you should think of the Format property as affecting how the data is presented to the user, not how it is stored in the database. Nevertheless, if you set the Format property of a calculated control to a numeric or date type, Access will recognize and process the data correctly. This works for unbound controls as well: Set the Format to "Short Date", and Access will not accept an invalid date. Set the Format to "General Number", and the user cannot enter a non-numeric value. In VBA Code Whenever you work with Variants, there is a danger that the data type can be misunderstood. Variants do have a subtype, so the problem is less prevalent than with calculated fields, but it is still good practice to explicitly typ

Width and Height are pulled from the table the report is bound to, whilst Area should be calculated (height * width). I've set the Control Source of the Area to = [Height] * [Width], but on opening the form the field displays #Type!, in typically descriptive #error in access Access errors fashion, with nice use of # and ! to make it impossible to accurately Google... but I digress. I have no idea what #Type! means and Access doesn't want to tell me. I can't understand this. In the bound table, Height and Width are Integers, and are both populated in the record being viewed (so it's not a NULL problem). If I change the Control Source to something really simple - like =[Height], it spits out #Error! instead (again, thanks for the useful intel, Access. We'd be lost without you). Even = 1 spits out #Error!. Any idea why Access hates my control sources? ms-access ms-access-2010 share|improve this question edited Oct 31 '13 at 15:41 asked Oct 31 '13 at 15:20 Kai 96121128 add a comment| 3 Answers 3 active oldest votes up vote 2 down vote accepted You probably have a name clash, i.e. Access is picking up the Width and Height members of the report object rather than the fields called Width and Height. I would create a new query and simply rename the problematic fields in it. So, if you're using the query designer, add the primary key and any other non-problema

The field is not calculated in any way. Here are a couple of the things I've tried: =Sum([txtWeldInches]) =Sum([WeldInches]) =Sum(CDbl([txtWeldInches])) =Sum(CDbl([WeldInches])) ...well you get the idea. Each iteration I've used results in the Text Box displaying #Error Without exception. I've used similar constructs in different forms in the same project, so I'm not sure what the problem might be. Has anyone run into this before? EDIT: I ended up writing a VBA routine to update the boxes when it was likely that they would be changed rather than trying to get a bound sum() function to work. ms-access ms-access-2007 share|improve this question edited Sep 3 '09 at 18:59 asked Sep 2 '09 at 18:25 Rister 391310 add a comment| 4 Answers 4 active oldest votes up vote 2 down vote accepted Is the field "WeldInches" existing in the data source for this form? What datatype the field "WeldInches" is? EDIT: I have looked at all your comments. If it doesn't work by databinding, try and use the unbounded way. At runtime, get the value of WeldInches using DSUM and set the footer textbox's value when the form loads. Also, remember to update it at places where you think the SUM could change. share|improve this answer edited Sep 3 '09 at 16:18 answered Sep 2 '09 at 18:27 shahkalpesh 25.9k23874 WeldInches is a numeric datatype (specifically a SQL Server float) and there are no nulls in the dataset. It also definitely exists on the form. It is what is populating txtWeldInches. –Rister Sep 2 '09 at 18:30 Try "=Sum(NZ([WeldInches], 0)). –shahkalpesh Sep 2 '09 at 19:14 I know that there are no nulls in the dataset for this to make a lick of difference but I tried it anyway and i
