Parameters: Users must choose one or both parameters

I have two date parameters in my report. The user must make a selction on at
least one of the two parameters (either one), but does not have to make a
selection on both.
How do I verify that at least one parameters has a value? I guess this must
be verified on a pre-Execute event on the View Report button.
Thanks in advance for your help.Allow Null on both dates. Then in your sproc (which is essentially what the
query turns into) check both are not null, else raise an error.

In the receiving procedure on the SQL Server I will have to check if at
least one of the two parameters has a value. If not I raise an error in the
stored procedure. This error is automatically caught by Reporting Services
and displayed to the end user.

A dialog box would be better (maybe), but that is what we have.
