Returns a Boolean value indicating whether an expression> is an error value. Syntax IsError ( expression ) The required expressionargument can be if error then vba any valid expression. Remarks Error values are created by converting real numbers to error values using the CVErr function. 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. Example Note: Examples that follow demonstrate the

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.

Subscriptions My stuff Preferences Send a message Log Out Microsoft Use Nz() to replace an error message in Access A missing value can lead to confusion by returning error values. But a properly used Nz() function can https://support.office.com/en-us/article/IsError-Function-40a89200-138b-4e60-b254-34aea51b2e6b 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 scratching http://www.techrepublic.com/blog/microsoft-office/use-nz-to-replace-an-error-message-in-access/ 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.

See solution in other versions of Access: Access 2007 Access 2003 Question: In Microsoft Access 2003/XP/2000/97, I'm trying to write a formula in a query as follows: [Price]/[Quantity] Most of the times this formula works, but in some cases the [Quantity] field is zero so when the formula divides zero by zero, the result comes up as #Error. Is there a way I can tell Access, if dividing by zero, the result is zero? Answer: You can use the iif function in your Access query to handle these cases. We'll demonstrate how to do this with the example below. In this example, we've used the iif function to return 0 if the [Quantity] is 0. Otherwise, it would return the value of [Price] divided by [Quantity]. This is achieved with the following formula: IIf([Quantity]=0,0,[Price]/[Quantity]) Now, your Access query should no longer return an error when a [Quantity] of 0 is encountered.
