Dynamically changing Parameters based on user selection.

[jotek]

Is there a way to add a parameter or suppress a parameter depending on what the use selects from another user parameter? I want to allow the user to pick the report type but depending on which report option they select they need to fill in another parameter.
(The answer can't be database driven or create two seperate reports, thanks)
I am using CR 8.5 only

If the second parameter is only required when the state of the first meets a certain criteria (i.e. has a value of 1) what effect would there be if you were to set the second parameter and not use it (guessing that if the first parameter does not meet the required criteria then it is not used) ?
Are you not simply able to blank the second parameter in cases when the first meets the required criteria ?

You are correct. But I do not want the user to see the other parameter. They get confused by seeing this extra parameter. So by just not filling it in, is technically not a problem since it doesn't get used depending on what they select. I just want a way to make it easier for the end-users.
So I am still looking for a way to do this.

People have often asked for this but I don't believe that Crystal can do it. There's no front-end programability to a Crystal Report as you might have in some more expensive tools.

Your only choice is using a front-end end like VB. Or dealing with the user not entering values for certain parameters.
