[AccessD] NZ for Null

Virginia,

I agree with Arthur and Dan.  I can't see the beginning of this thread, 
so I'm not sure whether this expression is being used in code, or in a 
calculated field in a query, or in the Control Source of a calculated 
textbox on your report.  Anyway, something else to bear in mind is that 
the Nz() function returns a string, so it is sometimes tricky.  If you 
want the result to still behave as a number (e.g. to apply number 
formats etc), you have to convert it back to a numerical value again, 
typically by wrapping it inside a Val() function.

Regards
Steve
