I am creating a simple Jigsaw puzzle in part of a navigation system for a trivia page. previously in action script 2.0 you could use the eval method. I have changed the most part of my code to be compatible with 3.0 by changing my eval classes to \*\*this[“myMovieClip”+ i]

**However I am uncertain what to do for part of my IF statement** , \*\*I am relativley new to using flash and I am stuck here is the code so far (Note the part I am stuck on is in bold text) thanks for any help 🙂  
var noOfPieces:Number = 24;  
var selectedDepth:Number = 50;

//Loop to assign.  
for(var i = 1; i \<= noOfPieces; i++) {  
//Randomly places the pieces.

```
this["myMovieClip" + i + "_mc"]._x = Math.ceil(Math.random()*600) + 100;
this["myMovieClip" + i + "_mc"]._y = Math.ceil(Math.random()*400) + 100;

//assign a depth to each piece.
this["myMovieClip" + i + "_mc"].swapDepths(i);

//assign an ID to each piece.
this["myMovieClip" + i + "_mc"]._id = i;

//assign variable to check wether solution is solved or not.
this["myMovieClip" + i + "_mc"]._solved = false;

//drag when pressed.
this["myMovieClip" + i + "_mc"].onPress = function (){
this.swapDepths(selectedDepth);
this.startDrag();
};

//stop the drag when released.
this["myMovieClip" + i + "_mc"].onRelease = function(){
this.stopDrag();
    
    //check to see whether the puzzle is in place.
[SIZE=4] **if(this.hitTestObject(eval("p" + this._id + "h_mc")._x, eval("p"+ this._id + "h_mc")._y, true)){**[/SIZE]
        //auto align
        this._x = this["myMovieClip" + this._id + "h_mc"]._x;
        this._y = this["myMovieClip" + this._id + "h_mc"]._y;
        
        //puzzle is in right place.
        this._solved = true;
        //push the depth to lower levels
        this.swapDepths(- this._id);
        //check whether all have been solved
        checkSolution_fn();
        
        //disable event handlers
        delete this.onPress;
        delete this.onRelease;
    }else{
        //not solving
        this._solved = false;
    }
};

```
