I am trying to do a simple calculation in a query. it is dividing one field by another to come up with a rate. When I do that I get a message box that says "This expression is typed incorrectly, or is too complex to be evaluated. For example and numeric expression may contain too many complicated elements. Try simplifying the expressiong by assigning parts of the expressiong to variables." Why would I get that message on a simple expession? I tried to enter in sql and directly in the query. What am I doing wrong?
