I am trying to create collision detection between mcs without having to write the code 10 times.  
I thought this would work but it gives me this error:

TypeError: Error #1034: Type Coercion failed: cannot convert “crisisAnimation” to flash.display.MovieClip.  
at ImagineServicesText2\_fla::MainTimeline/hitTester()

```auto
var target_mc:Array = new Array();
var numTextBoxes:Number;
target_mc = ["crisisAnimation","eventTextAnimation","mediaRelationsAnimation", "mediaAnimation", "graphicAnimation", "webAnimation", "advertisingAnimation"]; 
// 
function hitTester(event:Event):void { 
numTextBoxes = target_mc.length; 
for (var i:int =0; i<numTextBoxes; i++) { 
var textA:MovieClip = target_mc*}; 
for (var j:int =i+1; j<numTextBoxes; j++) { 
var textB:MovieClip = target_mc[j]}; 
//temp_A = eval(textA); 
//temp_B = eval(textB); 
if (textA.hitTestObject(textB)) { 
trace ("Hit!"); 
}
}
this.addEventListener (Event.ENTER_FRAME, hitTester); 

```
