Urgent help please with MIDI pedal

Question

I just got an old awesome midi pedal called the X-15 Ultrafoot.
The pedal has two expression pedals, and 10 pushbuttons/pads. (and two buttons to cycle through additional banks, and a "mode" and "bypass" button)
Somebody please help I am on the verge to having amazing control.
What I want to do is have each pushbutton be assigned to a parameter, which is easy to program. Then I want to make the expression pedal(s) also be assigned to that last selected parameter. How do I do this?
How can I make the expression pedals control over the parameter remain exclusive to just the last selected parameter?!
Somebody save me please thanks

mr kglad i really hope my ( too many replies and questions ) don't bother you.. but please excuse me if they sound foolish or something im a beginner as mentioned...
There must be something wrong with whatever im doing ... ( im so desperate and since you are the only one who replied on me i really need your help please.. )
1- i published the first fla as a swf (10.3 ) with a button with the code you've given me )
2- i published the second fla as a swf (10.3) with another button with the same code you've given me )
3- i made a main page where there are two buttons.. one for english and one for foreign language
  English button with this code :
Engbutton.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF_4);
import fl.display.ProLoader;
var fl_ProLoader_4:ProLoader;
//This variable keeps track of whether you want to load or unload the SWF
var fl_ToLoad_4:Boolean = true;
function fl_ClickToLoadUnloadSWF_4(event:MouseEvent):void
    if(fl_ToLoad_4)
        fl_ProLoader_4 = new ProLoader();
        fl_ProLoader_4.load(new URLRequest("englishformFIN.swf"));
        addChild(fl_ProLoader_4);
    else
        fl_ProLoader_4.unload();
        removeChild(fl_ProLoader_4);
        fl_ProLoader_4 = null;
    // Toggle whether you want to load or unload the SWF
    fl_ToLoad_4 = !fl_ToLoad_4;
and the other button with the same code ( the second fla )
IT DOESNT WORK WHEN I TEST THE MOVIE.. the return buttons nor the main ones..why why why why why... ???
i really need your help
