Movie Clip Jams Up

Hello everyone, “AS” newbie here. I have an issue with some AS. At this address:

As you roll over your mouse progressively faster over the building(s), the individual highlights for the buildings (movie clips inside the main movie) seem to jam up. I have frame rate at 30 which I don’t want to go any faster unless I need to. I think its an issue of my Action Script. The below address:

http://midwestwebdesign.net/temp/test.htm

Shows my new Action Script, which is verison 7. Basically I’ve created a function that will allow my building to utilize the _visible property, true is they are shown, false if not. But I can’t for the life of me figure out how to call the individual highlight movie clips inside my main timeline to actually show the highlight. The AS for the function I believe is fine, just missing one part.

The function looks like this in the main timeline:


var clipNames=["graff","lincoln","ic","ice","icw","tec","cec","bic","ittc","childcare","bookstore"];//etc...

function setHighlight(clip:String){
     // here we pass in a string for the name of the clip we want to highlight
     // ie: "graff"
	"graff"
	"lincoln"
	"ic"
	"icw"
	"ice"
	"tec"
	"cec"
	"bic"
	"ittc"
	"childcare"
	"bookstore"
     // next, loop through the array
     for(var i=0;i<clipNameslength;i++){
          
          // if the string passed in matches the current array item, highlight it
          if(clipNames*==clip){
                 this[clipNames*+"Hovermc"]._visible="true";
          }
          
          // if not, turn it off
          else{
                this[clipNames*+"Hovermc"]._visible="false";
          }
          
     }
}
// this will turn off all clips to start
setHighlight(null);

this.graffBtn.onRollOver=function(){
		
		_parent.setHighlight("graff");
}


The way I target the movie clip building is like so:


_parent.setHighlight("graff");

The individual movie clips are two frame sequences, with the first being stop and the second frame showing the code above. I would appreciate any feedback or suggestions.
