what does the overflow error message mean?

[Duane Hookom]

It means what it says. Please use the large white space to describe your
issue. It helps to know if this occurs in a query or code or form or report
or...

 

[John W. Vinson/MVP]

As Duane says, a clearer question is always helpful. You can see your
database; we cannot.

Overflow means that you have calculated a number which is larger than Access
can represent. Often this happens when you have a mathematical expression
which isn't doing exactly what you intend it to do! Dividing a large number
by a very small one can cause this error, among other things.

If you're getting the error from a Query, please open the Query in SQL view
and post the SQL text here.
