Can one prompt "disable" another?

[DTV12345]

Hello!

I have a very simple report with 2 prompts I named "PRODUCTSprompt" and "REGIONSprompt".

Is there a way to make so that if my user selects a value from, say, "REGIONSprompt", the widget for "PRODUCTSprompt" becomes disabled or read-only?

TIA,

Alan. ???

How about building two prompt pages? You can then conditionally render specific objects on the second page based on values selected on the first page.
