Flash as2 to as3 attachMovie code problem

Hi guys,

I am making a game in which I am creating several random placed movie clips directly from the library to the stage.

I am a good as3 developer and can understand most as3 concepts except for arrays. But I cannot find a workaround for the attachMovie()

The code which causes the problem is as follows.(I have excluded other pieces of code)

// object is the name of my movie clip

var objectNumTracker = 1;

var depth = 555;

current_object = attachMovie ("object", "object" + objectNumTracker, depth)

objectNumTracker ++;

depth ++;
