Using _level

hi :slight_smile: …as the title suggest, I’ve made a simple flash just to learn how to control another swf file from root using _level actionscripts, it’s containing 2 file, one is the main.swf and the other (named bur1.swf) is loaded on the main using loadmovienum action. on the main swf, I made a three button that could control bur1.swf timeline (using _level actionscripts) but the problem is, I could not make it work at all… I would like if some one could see if I had done anything wrong.

any help is really appreciated…
thank you in advance…
