Loading External SWFs controlled by MovieClip Buttons

Wutsup doods,
Alright this is pretty much the last thing I am going to need help with for my site, so anyways, I basically made movie clip buttons to navigate through my site, has sounds and all…now all i need those buttons to do is to call out a .swf file from a certain directory. I know how to do this with the traditional button, but not with a movie clip button since it requires a function. This is what I have tried and failed with so far:


// PROFILE SECTION BUTTON //

this.profile_mc.onRollOver = function(){
profile_mc.gotoAndPlay("_over");
}

this.profile_mc.onRollOut = function(){
profile_mc.gotoAndPlay("_out");

this.profile_mc.onRelease = function() {
profile_mc.loadMovie (“profile.swf”,“placeholder_mc”);
}

// PROFILE SECTION BUTTON //

The 1st two lines of code work which controls the animation of the button, but the last script is where I am confused. I want to load the external swf “profile.swf” into the “placeholder_mc”, so yeah that is the problem.:?)
