SYMPTOMS

When you attempt to run a query, a form, or a report, you may receive one of the following error messages:
Overflow
or
#Div/0!

CAUSE

This issue can occur because under certain circumstances, a division by zero (0) can show the Overflow error or the #Div/0! error in the control. The error can occur in queries or in calculated controls on a form or a report. In many cases the field value of zero is the correct data.

RESOLUTION

To resolve this issue, use an Immediate If (IIF) statement to trap the error:

Assume that Field A is to be divided by a divisor field that can contain a value of zero. To avoid a division by zero, create an expression field that is set up like this:

=IIF([Divisor Field]=0,0,[Field A]/[Divisor Field])

This IIF statement tests the divisor for a value of zero. If the value of the divisor is equal to zero, the statement returns a value of zero without performing the division. If the value of the divisor is not zero, division occurs normally.
