[RESOLVED] combining variable with sting for html textfield

[calmchess]

I'm using the following code to try and change the font size of a textfield dynamically using a varaible but I can't get size to use the variable as a value however all the other variables I combine with the string works as intended just not size .....can somebody spot the trouble plz.

 var chSize = 50;
              trace(msg);
                insID.htmlText += "<font size="+chSize.toString(16)+" fontFamily='Tahoma' color=\"#"+newColor.toString(16)+"\">"+msg+"</font>";
                 insID.wordWrap=true;
                stage.focus = msgOut;
                scrollBar.update();
