Swap depth problem

for base.swf the script is:
and load porta1 in _level1 and porta2 in _level2

both movies (porta1 and porta2) have the same script: this.swapDepths(this._parent.getNextHighestDepth() );

also try with: this.swapDepths(999);

the output panel shows that dephs change but i still see porta2.swf in fornt of porta1.swf

i think is a path problem… or maybe there is another form to see the same efect
