Topic: Clearing parameter values Posted: 16 Feb 2012 at 12:01pm
I have 2 parameters on my Crystal XI report. Values are input for the parameters and the report is run.
When I click 'Refresh' and select 'Prompt for new parameter values' the input boxes for the 2 parameters appear BUT they are populated by the previous values.
Question - Is possible to have the previous values cleared from the parameter input boxes each time the report is refreshed ?

I don't, however, that does bring up a good point. I tried setting the Parameter default to a space but, on refresh, it still comes up with any initial entry made by the user. I tried the same thing with a period; same result. I am confused as to how the default value is supposed to work.

I haven't used the parameter screens in years, but I would think that the default values would be the value displayed when the report is first run (not subsequent runs as you noted they retain values).
I was going to suggest the value if you leave the parameter blank or check the is null, but either of these would return either the blank or the null value.
Again, I haven't used those screens in years, so I could be completely off my rocker.
