The IsError function is used to determine if a numeric expression represents an error. IsError returns True if the expression argument indicates an error; otherwise, it returns False.

use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box. This example uses the IsError function to check if a numeric expression is an error value. The CVErr function is used to return an Error Variant from a user-defined function. Assume UserFunction is a user-defined function procedure that returns an error value; for example, a return value assigned with the statement UserFunction = CVErr(32767), where 32767 is a user-defined number.

For example:SELECT (foo/bar) * 23 As ExpFROM TableThe expression will be defined by the end user so I would like to trap an error that may/will occur due to wrong syntax, divide by zero, etc.I've attempted the following:SELECT IIF(IsError((foo/bar) * 23),"", (foo/bar) * 23)FROM TableMy thinking is that the IsError will evaluate the expression and return "true" if an error occurred or return "false" if an error did not occur. The IIF function will then evaluate the IsError result and finally return an empty string if an error did occur, or return th

But a properly used Nz() function can turn an error message into ms access 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 scratching their heads and reaching for the ms access iserror 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.
