Trying to eliminate Parameter prompt so I can run report unattended

I have inherited some reports, and being a Crystal novice I am not sure how to accomplish this task.
I have a report that shows three parameters... Which Warehouse, Which Period and Detail or Summary.
With Select Expert>record I am able to designate the WH that I want. Sure enough After doing that the WH field does not show up in the prompt but the Which Period and the Detail or Summary are still there. They are formulas as shown in the picture. Can someone tell me how I can hard code this so the prompt never comes up?
