Tracing image loaded from loop?

Hey! Thanks for looking at my post.

I have a loop within a loop as you can see below. I am trying to trace the images so that each one comes up:
video0
video1
video2
video3 (etc. - there are a total of 9 images indicating videos).

But the way that I have it tracing right now does not bring up the names as I want them. You will probably be able to see why after looking at the code below.

Here is my loop:

[AS]
for (var i=0; i<rows; i++) {

 for (var j=0; j&lt;columns; j++) {

      imageHolder = new MovieClip;
      imageHolder.x = leftMargin + j * imageWidth * marginX;
      imageHolder.y = 290 + i * imageHeight * marginY;

      addChild(imageHolder);
      imageHolders.push(imageHolder);
 }

//this is what I currently have but I know its not right. Just not sure how to make it right.
//I tried different ways of doing it such as putting a trace in the second loop.
imageHolder.name = “video”+ i + j;
trace (“video”+ i + j);
}
[/AS]

So, if you know why mine is wrong and the right way to do this. could you pls explain this to me.

Much appreciated!
