problems converting a string into a movieClip name

[Lizzie.Fellows]

My code is below. I have an external Class AS file doing most of my code but I need some of the moviClips to highlight areas (other movieClips) when they're rolled over.

I've kept instance names the same + an H for their highlights to lessen the amount of code and be able to use array's and for loops.

my code is below and brings up this error:

TypeError: Error #1034: Type Coercion failed: cannot convert "areanaH" to flash.display.MovieClip.
    at EnterpriseZone_fla::Layer1_1/end()

please help...

import flash.display.MovieClip;



function hArea (e:MouseEvent) {
    var mName:MovieClip;
    mName = MovieClip((e.target.name) + "H");
    mName.gotoAndStop(2);
    
}


function end (e:MouseEvent) {
    var mName:MovieClip;
    mName = MovieClip((e.target.name) + "H");
    mName.gotoAndStop(1);
    
}

var stopAll:Array = new Array (bHomes1H,areanaH);

for (var i:int=0;i<stopAll.length;i++){
    stopAll[i].stop();
    
}

var rollArray:Array = new Array (bHomes1,areana);

for (var Mc:int=0;Mc<rollArray.length;Mc++){
    rollArray[Mc].addEventListener( MouseEvent.MOUSE_OVER,hArea );
    rollArray[Mc].addEventListener( MouseEvent.MOUSE_OUT,end );
}
