Multiple Buttons

[FONT=Arial]Hi All,[/FONT]

[FONT=Arial]I’m fairly new to flash so please bear with my ignorance. On the stage I have placed a movie clip called links, inside links there are 4 movie clips (mc1, mc2, etc.), each one of these movie clips has a button in it (btn1, btn2, etc.). I have scripted the first button so that it loads an .swf in level 1. Once the external file is loaded in level 1, I can still access the buttons, what do I do to disable all 4 buttons when there is an external file in level 1?[/FONT]

[FONT=Arial]Thank you for your help.[/FONT]
