SSRS and two different parameter issue

Question

Hi,

I have two parameters using two different datasets. One is where you select a Sales Rep and one is where you select Account Manager to show their sales. I want to show all records that match the Sales Rep or Account Manager that are selected. Some are Sales Rep are also in the Account Manager list. Is there a way to make sure if that all records are being picked up if the pick one or the other easily?

Thanks for any guidance.
