Hi,

When I'm opening a report I get the message "This expression is typed 
incorrectly, or it is too complex to be evaluated.  For example, a numeric 
expression may contain too many complicated elements.  Try simplifying the 
expression by assigning parts of the expression to variables."

I'm using Access 2007 (just upgraded from 2003).  I didn't seem to get this 
error in 2003.  This report is based on some 3 queries.  
- The 1st query runs and limits the data set to dates that are selected in a 
combo box on a form.
- 2nd query runs and sums the data for all dates within the data set.
- 3rd query runs and calculates some percentages, etc.  
The queries work great and when I run each of them and they gives the 
information I need without a problem.  But, the report that this last query 
is based on gives the message above.  Any ideas what could be causing the 
problem?

Thanks!
Heather
