Calling moive from array for attachMovie property

Dear forum members,

I am trying to attachMovie from array.

Here it goes like this:

var __reg3 = new Array (“1”, “2”, “3”, “4”);

_root.p1.attachMovie(__reg3[0] + 1, “run1”, 1); – Not working

Then I tried using string:

test1:String = __reg3[0] + 1

_root.p1.attachMovie(’"+‘test1+’"’, “run1”, 1); – Not working

Then I tried this

_root.p1.attachMovie(" “” +test1+" “”, “run1”, 1); – Not working

Then used this:

qt:String = ‘"’;

_root.p1.attachMovie(qt+test1+qt, “run1”, 1); – Not working

But when I use like this, its working:

_root.p1.attachMovie(“3”, “run1”, 1); – working.

Please help guys.
