Hi Joe,

Looking at your issue, I can guess that you want Multivalues to be working for your reports....

Actually, Multivalue parameters works when we use IN with them...

It seems that you are using EQUAL within your query that's why you are receiving the error after execution of the report..

I would advice you to use IN with Multivalue parameters b'coz it then splits the selected multiple values with a ',' [Comma]...and executes the concerned dataset..

You can try it and let me know if it works.

Cheers,

Niraj
