> please help me! it's really simple

please help me with this one:
i guess it’s called “movieclip swap depths”. Im in the middle of a project and this is really blocking me.
check the swf:
http://www.rf-13.com/help/mc1.swf
I need the mc2 [the photo] to cover the mc1 completely. I don’t want the mc1 menu appearing when mc2 is loaded.
same to mc2: when I go back to mc1, I want mc2 to disappear. Please send me the code so I can copy to make it work.
Im sure this is really simple, but Im new to flash and I need your help.
thanks.
