Help me with meh Gridlist :P

[yayo]

Ok, so I have my menu, gridlist, and "OK" button all setup for my clothes store, but I cannot seem to figure out how to make it so that when you select your clothes by clicking each item on the gridlist, and then hit the OK button, it will give you what is selected on the gridlist. If you understand my problem please help me out. Heres my code if it helps...
