versions of Access, that meant changing: =Sum([Amount]) to: =IIf([Form].[Recordset].[RecordCount] > 0, Sum([Amount]), 0) Access 2007 and later have a bug, so that expression fails. You need a function. Copy
Access Iserror Function
this function into a standard module, and save the module with a name such as Module1: Public Function FormHasData(frm As Form) As Boolean 'Purpose: Return True if the form has any records (other than new one). ' Return False for unbound forms, and forms with no records. 'Note: Avoids the bug in Access 2007 where text boxes cannot use: ' [Forms].[Form1].[Recordset].[RecordCount] On ms access #error in sum field Error Resume Next 'To handle unbound forms. FormHasData = (frm.Recordset.RecordCount <> 0&) End Function Now use this expression in the Control Source of the text box: =IIf(FormHasData([Form]), Sum([Amount]), 0) Notes Leave the [Form] part of the expression as it is (i.e. do not substitute the name of your form.) For Access 97 or earlier, use RecordsetClone instead of Recordset in the function. A form with no records still has display problems. The workaround may not display the zero, but it should suppress the #Error. In reports Use the HasData property property, specifically for this purpose. So, instead of: =Sum([Amount]) use: =IIf([Report].[HasData], Sum([Amount]), 0) If you have many calculated controls, you need to do this on each one. When Access discovers one calculated control that it cannot resolve, it gives up on calculating the others. Therefore one bad expression can cause other calculated controls to display #Error, even if those controls are bound to valid expressions.

I have a query set up to do several http://allenbrowne.com/RecordCountError.html simple but time consuming calculations. There query determines the volume in the tank at the start of the fall based on a measurement, the volume in the tank at the end of spring based on another measurement, and I would like it to determine the methanol usage over the time period. Since methanol may be added during the winter if the storage tanks get http://www.access-programmers.co.uk/forums/showthread.php?t=191477 low I sometimes need to add a fixed number(s) to the difference of the two fall and spring volumes. The problem I am having is that not all the tanks get refilled during the winter months. I am using a DSUM function to calculate the total amount of methanol added between the spring and fall dates. If the tanks don’t get refilled, the DSUM function appears to return a null or an empty entry, then when I add the three fields FallVolume, Spring Volume, and AddedMethanol, I get a #Error in the calculated field MethanolUsage. I have tried using IIf(Iserror([AddedMethanol], as well as both IIf(IsNull([AddedMethanol and IsEmpty(). These don’t seem to work help either. I have also tried using the Nz function when calculating [Addedmethanol] and forcing it to return “0.00” if it results in a null value. I have searched the forum and the web and have come up empty so far. At this point I am stumped why it is not working. Any help would be much appreciated. Thanks, Mike MethanolUsage for the first record should be 1085.05 FallVolume: FormatNumber(DLookUp("[Volume]","[tblTankGaugeCharts]","[DipDepth]=" & [FallDipReading] & "And [TankID]=" & [MethanolTankID]),2,0) SpringVolume: FormatNumber(DLoo

I need to know if the thing I am looking at is a number or text. If it's text I want a zero, if it is a number I want ms access #error the number. I know that when I use FormatNumber([C107_62xx]![F40]) on a text line I get an error. I would assume when I get an error, then my iif formula above would convert that to a zero and the world would rejoice. For some reason I am still getting a #error even with my iif statement. What am I doing wrong? I have also tried using the IsNumeric function but I still get #NUM! errors that come through. function ms-access ms-access-2010 share|improve this question edited Mar 26 '14 at 19:16 HansUp 79.3k114371 asked Mar 26 '14 at 18:49 Nigel 2041211 add a comment| 1 Answer 1 active oldest votes up vote 5 down vote accepted IsError does not do what you think it does. From the help topic, it "Returns a Boolean value indicating whether an expression is an error value." Not whether the expression triggers an error, but whether the expression is an error value. Sorry, that explanation was probably not clear enough, but I don't know how to do better. So I'll just suggest you consider this IsNumeric() expression for what you want here. IIf(IsNumeric([62xx]![F40]), FormatNumber([62xx]![F40]), 0) Here is that same expression in a query with the output below. SELECT [62xx].F40, IIf(IsNumeric([62xx]![F40]), Forma
