I believe the problem I am experiencing at this point is this.

Each row is referencing every single value selected from multi value parameters and I only want it to reference one for each row.

This is because all the datasets are set up with WHERE RMPROPID IN (@PARAMETERS), thus using every property that was selected...

Even with group by PropID on the detail row of the table, I just don't know how to make the datasets only reference 1 property at a time.
