I have a report with {comment} fields. I want to create an optional parameter that excludes line items that have a comment field that include the word "Screen". I have played around with a NOT LIKE "*Screen*" in the Select statement and that works fine but i am not sure how to make this work based on a optional parameter entry. Suggestions????

In your example is "filter" the parameter name or are you using the Filter function within crystal?

The word will always be "Screen". I just want to see the data associated with it sometimes and not see the associated data at other times.

Im not sure what a "Required Filter" is?

Thanks. That worked.
Ended up with this Select Statement.

({?Rmv_Spcl_Antgn_Ordrs}="N" or ({?Rmv_Spcl_Antgn_Ordrs}="Y" and isnull ( {Cmnd_cjb.COMMENTS}) or NOT({Cmnd_cjb.COMMENTS} LIKE "*Screen*")))

This works to still display my Null values for Comments and all of my Comments that do not in include "Screen" when the parameter is selected.

Thanks
