Error Message if Parameter Doesn't Contain Value(s)
Posted on 2013-06-27
I am using Crystal Reports 2008. I currently have a report request that has three parameter fields. All of the fields are "optional", but at least one has to be chosen (if that makes sense). If the user does not enter a value into at least one of the fields, the report is supposed to display an error message prompting the user to enter a value. I have an alert set, but the report has to run before it is evaluated so that doesn't work. Is this possible?
