Need help on script

hi guys…I got a cool script that can make button to stay down after you click it…but the problems is if I want to use that button to load a .swf movieclip into the main clip, the button does not work as I expect.
plz see the file that I attached…in that file you can see the 1st and 2nd button can load the movieclip into the stage, but the button color doesnt change as you can see in button no 3 - 8 (i didnt put any movie clip for button 3-8)

can anybody help??
thanks heaps
