FMX-transition problem

Please can someone look at the code, and say what is wrong, I´m trying to adapat some code I grabe from this forum. Itá a transition problem whit levels. The movie starts whit a filled mc, then when i press a butoon iy´s supossed to have a preloader that loads the movie, then oen the mc, if i click other button the boxxes closes and loads the other swf then opens, and so on.

I really can figure it out, so please can someone look at this.
