MovieClip Compile Error

Good evening,

Sorry for a newbie question, but that's what I am!  I am attempting to create a single frame movie clip that contains 3 dynamic text fields.  In the MovieClip class I need to modify the contents and format of the text fields.  My code has no syntax errors, but it does not compile.   Here is my code:

package 
{

import flash.display.MovieClip;
//import fl.controls.TextArea;
//import flash.text.TextField;
 
public class FactProblem extends MovieClip
{
  private var txtT1:String="a";
  private var txtT2:String="b";
  private var txtT3:String="c";
  private var locX:Number=20;
  private var locY:Number = 20;
  //private var t1:TextArea;
  //private var t1:TextField;
 
  public function FactProblem()
  {
   with (this)
   {
   x = locX;
   y = locY;
   //t1.text = txtT1;
   //t2.text = txtT2;
   //t3.text = txtT3;
   }
  }
}
}

As you can see from my code I tried importing TextArea and TextField, but the problem persists.  as the code exists, this is the error message:

ReferenceError: Error #1056: Cannot create property t1 on FactProblem.

Your suggestions would be greatly appreciated.  For the past three days I've not been flashing; I've been stumbling in the dark!
