Print detail lines horizontaly 1

[ianoctdec]

Hi everyone,
I want to print detail lines horizontaly. My report has three groups
Group1 - PartId
GRoup2 - Whse
Group3 - Loc
Detail - TagNo
Instead of having: A1 B C
1
2
3
I would like to have: A1 B C
1, 2, 3
For different groups, detail can have one or more lines, that is each combination PartID, Whse, Loc can have one or more tags. I guess a formula that concatenates all TagNo per group should do it, but I can't make it work. PLease help me!
I use Crystal 10, Oracle db, ODBC connection,

Thank you for your help,

Dana
