Trying to name a variable

I have a 2 frame movie. It’s basically drag and drop movieclips onto targets and see if they’re correct. When the draggable movie clip is dropped onto the correct movie clip, the user clicks a done button and sees if they got it right or wrong. An if loop is checking which are correct. What I want to do is to assign the correct targets on the first frame and then these will be used to name the variables on the done button.

First frame:


var ans1:Number = 1; 

Here’s the code for the button:

on (release) { 
//if the draggable object 1 is dropped on the correct target (1)     
if (this.Drag1._y == this.Target+_root.ans1._y) 
{  
//CORRECT, display a correct sign         
this.tick0+_root.ans1.gotoAndStop(1);     
} else {  
//WRONG, display incorrect sign         
this.tick0+_root.ans1.gotoAndStop(2);     
}
 } 

I know this is completely wrong, I don’t know how I should do it. Can anyone help a beginner out?
