font size not working...*&^%$

Hi all,

I don't know whats going on but my code is not changing the size of my text.

I have a toggle button that works great on everything exept the text size.

I have a text dynamic text field called myText and here is the code I'm using.

function maisLegendaF(e:MouseEvent):void{

          var formatT:TextFormat = new TextFormat();

  if(!e.currentTarget.toggle){

  myButton.gotoAndStop(2);

                    formatT.size = 19;

                    myText.setTextFormat(formatT);

          }

  else {

                    myButton.gotoAndStop(1);

  formatT.size = 12;

  myText.setTextFormat(formatT);

          }

          e.currentTarget.toggle = !e.currentTarget.toggle;

}

Can anyone help me out here? PLS?

Thanks in advance!!!
