[COLOR=#000000][FONT=Arial]HI I wanted to resize my drawRect function based on text characters in my radio button group. I have this code:

[COLOR=#000000][FONT=Consolas]function chkAnswer(mevt:MouseEvent):void {[/FONT][/COLOR]

    cdlDone[index] = 1;    
   var rectSize:uint = 300;      // i don't know how to set up the width based on text
  var correctRect:Shape = new Shape();    
  correctRect.graphics.beginFill(0x00FF00, 0.5);   /* The user selected the "Show me the answer" button */   

if (cdlCorrect[index] == 0) { // Correct answer is the 1st radio button     correctRect.graphics.drawRect(45, 45, rectSize, 25);      / [COLOR=#000000][FONT=Consolas]            trace("This is 1st Radio button"); [/FONT][/COLOR]
