How to setup Multiple report layouts based on parameter selection

Question

I'm trying to create a report that will be based on the parameter values a user select. There will be 3 different layouts for the report.

Salesperson

If the user selects one of the three a different layout will be displayed.
This is probably a simple solution but my Reports 6i skills are a little rusty.
Your advise would be appreciated.

Ok so you have a parameter form, and some parameters. In the data model, you can put your 3 queries. In the layout, as Ino said, put all 3 frames that you could possibly have.
The way I would use to choose which query to use is below. Others may have other methods, but I like this.
Ok lets say you have query A,B,C for simplicity. You have one parameter (P_PARAM1) on the form, and the user can choose A,B or C. Based on the parameter, you choose which query to use.
In query A, you would add this line to the where statement:
and :P_PARAM1 = 'A' You add the same lines to queries B and C, but change the letter obviously. So if the user enters A, it will only run query A because that was the parameter selected.
Now for the layout, click on the frame that corresponds with group/query A. You would click F11 or launch the PL/SQL editor, and add the following format trigger (or something similar).
function F_GRP_A return boolean is
begin
  IF :P_PARAM1 = 'A' then
    return (TRUE);
  ELSE
    return (FALSE);
  END IF;
end;Ok - then add that same logic to Frame B and C, and based on the parameter it will hide or show the frame.
Hope that helps - thats a basic way to do what you're looking for!
