For each report control, you can specify "Pring When" condition.

In your case, you can do something like this..

LEFT(Field,2) <> "LP"

The program I have, mostly developed by a third party, prints out several reports from Cougar Mountain Accounting data files. The problem with the actual report is I need it NOT to print some entire entries, specifically any IN_STOCK numbers begining with "LP" and any entry that has a 0 total in iutotal. So the questions are:
>
>1: I know I need to modify the form to include the expresion to exclude, but do I need to place that expression in every field across the page, or just in the fields in question?
>
>2: How do I build said expression in the first place? Will logical functions work? Do I need to build it using some type of INLIST command, or somthing else?
