Access #num Error
this query so the result produces an #Error result as opposed to a blank or a negative. In Excel, I'd normally use an IFERROR formula to deal with this, but cannot find a reasonable equivalent of this in Access. The format would be something along the lines of '=iferror(x*y,"")' I have 'x*y', no worries Any help on a generic formula equivalent would be greatly appreciated, preferably in its most simple form #func access error - I know there are several noobs like me out there looking for an easy way around this omission.

In any event, they managed to get by with this omission up til 2003, by using an if() wrapped around an IsErr(). The only difference in Access is you wrap the if() around an IsError(), so: If(IsError(x*y),

But a properly used Nz() function can http://www.access-programmers.co.uk/forums/showthread.php?t=217455 turn an error message into an understandable and expected value. By Susan Harkins | in Microsoft Office, February 6, 2009, 2:14 AM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus Missing values can confuse users if handled incorrectly. For instance, a calculated control in a form or report has the potential to return #Error if a value is missing. That's going to leave your users http://www.techrepublic.com/blog/microsoft-office/use-nz-to-replace-an-error-message-in-access/ scratching their heads and reaching for the phone to ask what's up. You can avoid their confusion (and your interruption) by using the Nz() function to force a value — usually 0. This function's syntax is simple: Nz(expression, replacementvalue) where expression is the field or value being evaluated and replacementvalue is the value or text you want to display, or pass, when there's no value. (You can learn more about Nz() in Help.) I've found that applying Nz() correctly can be a bit of a puzzle for some folks. The key is to wrap every field or value in an Nz() function, not the entire expression. For instance, the following expression has the potential to return #Error, despite the Nz() function: =Nz(Sum(Price * Quantity, 0)) The correct syntax follows: =Sum(Nz(Price, 0) * Nz(Quantity, 0)) Wrap each field within the expression to catch each missing value before the SUM() function tries to evaluate it. Of course, the best solution is to prevent missing values in the first place. To do so at the table level, set the field's Required property to Yes. However, doing so isn't always appropriate or practical. That's when the Nz() function comes in handy — as long as you apply it correctly.

Hooray for The System! Hooray for Conforming! Replace #Error with 0 in Query : MS-Access tallgeeze Registered User regular March 2011 edited March 2011 in Help / Advice Forum Hello good H/A folks! The title says it all. Due to the if error function nature of the data combined with the math I have going on in the query I'm going to have a lot of "#Error" entries for my percentages. I'm just looking for a way to replce those entries with a 0 if at all possible. It would make the resulting reports neater to look at for my end users. I tried my hand at google, but the only legit result required me to sign up for stuff, which I don't want to do. Thanks in advance! tallgeeze on March 20110 Posts Daenris Registered User regular March 2011 edited March 2011 Don't know if this was in earlier versions, but if you're using at least Access 2007, there's an IsError function. http://office.microsoft.com/en-us/access-help/iserror-function-HA001228865.aspx So you can use an if statement to check if the value is an error, and return 0 if it is.
