Difficulty loading external SWF


I’ve been having difficulty getting an external SWF to load into a movieclip on my stage. The teal box is a movieclip with this particular instance named mcStage1. I put an identical teal box directly behind it on a lower layer for purposes of illustration that will become clear shortly. The small dark blue rectangle is a button that is supposed to cause an external swf, in this case “tester2.swf” to load into the space currently occupied by mcStage1.

I am trying to make a click on the dark blue button load an external SWF file into mcStage1. I have tried the following three methods:

Generated by Flash Behaviors

on (release) {

//load Movie Behavior
if(this.mcStage1 == Number(this.mcStage1)){

loadMovieNum(“tester2.swf”,this.mcStage1);
} else {
this.mcStage1.loadMovie(“tester2.swf”);
}
//End Behavior

}

***Written by me

***on (release) {

loadMovie("tester2.swf",_root.mcStage1);

}

***Also written by me

***on (release){
_root.mcStage1.loadMovie(“tester2.swf”);
}


In all three cases, the external SWF loads with its center at exactly the lower right corner of the target movieclip mcStage1. I created an identical square behind mcStage1 for illustrative purposes, as seen in the image below. It doesn’t matter where I move mcStage1 on the stage, it always loads in the same relative position. (note the red square in this case is my external swf, called “tester2.swf”)

Any help resolving this issue would be greatly appreciated!
