Simple actionscript BIG headache

[FONT=Arial]Hi guys - I found this forum around my 3rd hour of research while trying to fix an actionscript problem… I’m at the end of my rope. [/FONT][FONT=Arial]Anyone know why this isn’t working? It seems like the logical way to write it…Any help is appreciated.[/FONT]

_root.mymc.onRollOut = function(){
do {;
} while (_root.mymc._currentframe == 60);

[FONT=Arial]Frame 60 on “mymc” has a stop() action. The idea is to make mymc play if it is on frame 60 OR once it gets to frame 60 but only after the RollOut has occured.[/FONT]
