Button inactive then active GET IT :D

Hi guys,

Well i’m not much of programmer more a designer but i want to master flash actionscript. Kinda figuring out stuff but its the logic that bugs me. I got in me brain but cant seem to type it on screen :S. I attached fla for more details.
I have 3 buttons. When u press(release) button nr1. it go’s and stops a certian frame in a mc nested on its timeline. Now when i press (release) button nr2. i want button nr1. to go to ít’s normal stat en button nr2. to gotoandPlay acertain frame in a mc nested within its timeline. this vice versa end for nr3 well i think u kinda now what i mean.

Please have a look and c what me doing wrong.
Greag Great thanks
