#error In Access Report
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 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

Access Replace #error With Null
The Microsoft Access Nz function lets you return a value when a variant is null. Syntax The syntax for the Nz function in MS Access is: Nz ( variant, [ value_if_null ] ) Parameters or Arguments variant A http://www.techrepublic.com/blog/microsoft-office/use-nz-to-replace-an-error-message-in-access/ variable that is a variant datatype. value_if_null Optional. It is the value to use when the variant is a null value. If this parameter is omitted and the variant is a null value, the Nz function will return a zero or a zero-length string. Applies To The Nz function can be used in the following versions of Microsoft Access: Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000 Example Let's look at how https://www.techonthenet.com/access/functions/advanced/nz.php to use the Nz function in MS Access: Nz (varName, "n/a") The example above would return the value 'n/a' if the variable varName contained a null value. Nz (varName) The example above would return a zero-length string if the variable varName contained a null value. Example in VBA Code The Nz function can be used in VBA code in Microsoft Access. For example: Dim LOption As String LOption = Nz(varChoice, "Not Found") In this example, the variable called LOption would now contain value in the varChoice variable unless it was a null value. If the varChoice variable contains a null value, the Nz function will return "Not Found". Example in SQL/Queries You can also use the Nz function in a query in Microsoft Access. For example: In this query, we have used the Nz function as follows: Expr1: Nz([CategoryName],'Not Found') This query will evaluate whether the CategoryName field contains a null value and display the results in a column called Expr1. You can replace Expr1 with a column name that is more meaningful. So in this example, if the CategoryName field contains a null value, the Nz function will return "Not Found". Otherwise, it will return the value from the CategoryName field. For example: Category: Nz([CategoryName],'Not Found') The results would now be displayed in a column called Category.
