MovieClip.onRelease = MovieCLip.Protoype function fails to execute properly

programming flash

Dear all,

I created a simpe function:

MovieClip.prototype.hiMe = function(me, theRest)
{
//declare the format colors white and grey
formatMe = new TextFormat();
formatMe.color = Colors[0];
formatMe.font = “Adventure Subtitles”;

formatTheRest = new TextFormat(); 
formatTheRest.color = Colors[1];
formatTheRest.font = "Adventure Subtitles";

// assign grey to theRest
for (i =0 ; i < theRest.length; i++)
{
    theRest*.tfield.setTextFormat(formatTheRest);
}
// make the me white
me.tfield.setTextFormat(formatMe);

}

when I call it (bar[0] is an array of objects)
bar[0].invar.onRelease = hiMe(bar[0],bar);

it executes on load regardless of the onRelease eventHandler and the ownards it does not execute when exciting the event.

does somebody know why this may be?

Cheers

DDT
