Supressing parameter labels if not being used

[Stewman]

Hello all,

I am new to crystal and am using Crystal 10. I am running reports through an app that allows for parameters to be entered such as date, id#, and case number. I have labels for all the parameters and they show up on the report even if the parameter isn't being used.

For example, if I enter just a id#, I still have the date and case number label appear. The fields are empty but the label appears. How do I get it to not show the label if the parameter is not being used?

Thanks for your help,
Chris

Found answer from another post and worked great.

Isnull({vtaxid}) or length(trim({vtaxid}))=0

Just replace vtaxid with appropriate field name
