I have created a report which groups a listed of records based on their company then sorted by the state the company is within..

 

so

 

State(Group Header)

            Company(Group Header)

                        Records

 

I then have a parameter field so the user can choose which state to display as without this there is a lot of information to show. Once the user selects as an example, "IL" for Illinois it should display all the companies in Illinois and then none of the other states' information. Currently I have the parameter field created {Pm-Display} with the state selections, then a formula for "STATE DISPLAY" which reads as

 

if{?Pm-Display} = 'IL' then GroupName ({Multipay.State}) = 'IL' else if......for every state

 

where the GroupName{Multiplay.State} is what Im trying to only show information for the parameter field(state) selected

 

Any help would be appreciated
