When I input the criteria "Or Like" [blah, blah] "Is Null," it ends up including records that have a blank value in the field of the chosen parameter. For example, when I choose 4 for Corr, I get records with the Workload Corr and also records where the Workload field is blank. I need the effect of Is Null that gives me all workloads, blank or not, when I want the full report, but if I want to limit the report and select a certain workload, how do I limit the parameter query to not include workloads that are blank? See attached picture. I don't have Or Like, in it right now, since it wasn't working as desired.
