you will have to explain your data a little more, maybe some sample rows
and also give some samples of what kind of formulas you ended up with.
I am guessing you can do what you want without using an sub-reports but can't really tell until I see some data and how youa re counting it.
FYI- this is the wrong spot for this type of question so it was hard to find your post. Brian may move it into the correct location but future posts you may want to put in the '
Crystal Reports 9, X, XI, 2008' section and choose a sub forum there.
