whole number error?

[Shane]

When I enter a number higher than 155 into a particular cell, I receive a
message "must be a whole number", little message window with an X through a
red circle. Don't know if its a custom message created by previous user or
an excell error? How can I fix?

Perhaps look at 'Conditional formatting' and clear out any condition that has
been placed on that cell.

That sounds like a message from Data Validation applied to the cell.
Select the cell and click on Data | Validation then on the Clear All
button.

Hope this helps.
