Load Movie in target AND in level

My problem is this:

I have a button that must uppon being press go to the root lvl, find a target and open a movie in that target but in succesive lvls.

so, the ideal code would be…

on(release){
_global.lvl++;
_root.target1.loadMovieNum(“movie.swf”,_global.lvl);
}

But flash doesn’t allow me to do both at the same time, either i choose a target or a lvl, not both, and even less if the lvl is a variable.

This movie has some buttons that when pressed the open clips that should acumulate until closed.
