onRollOver font color change of dynamic text

programming flash

I have a movie clip that is acting as a button and the text is being pulled in by from an XML file. This text will be a clickable link. I’d like to change the color of the text in an onRollOver function but it’s not working. Any suggestions?

I’ve tried:

myFormat_fmt = new TextFormat();
myFormat_fmt.color = 0xE50000;

mod1Pop.onRollOver = function() {
	mod1Pop.mod1Title.setNewTextFormat(myFormat_fmt);
}

and it doesn’t work. also tried putting that in the actionscript of the movie itself with no luck.
