Hi Everybody,

I'm getting a headache trying to figure this out.  It may just be the way DP works, but this is what I need to do.

The company I do business with has come up with three catalogs for three separate product groups --- call them catalogs "A," "B," and "C."  My customer database has a parent record (name, address) and a child record (mailing list categories) containing one or more various categories which correspond to the product groups.  I want to create seven different lists of the following groups.

A
B
C
AB
AC
BC
A, B, and C.

I've done reports for years extracting names based on specific categories with subreports using Stop-Skip, but I can't figure how to do this. 

First I tried listing all the "A" categories  (using "contains") grouping them with parenthesis, then the "Bs," then the "Cs" and using "or" between the groups within one RV.  I then tested to see if the RV was true, but it's always false.  (Yes, there customers that fit the model.  I then tried moving the categories to three separate RVs, and then testing that RV with "and" statements to see if all three were true.  Still no results.

I haven't even tried to work out the formula for "A and B, but not C," etc.  If I couldn't get the one for A, B, and C, I figured, what's the use!

Could someone please guide me as to an approach that would work?

Thanks!

Charlie Wolf
