I have a simple bit of AS which duplicates MCs via looping through a couple of frames:

_root.tile.duplicateMovieClip("tile"+i,i+1)

What I would like to do is to use a button to move each duplicated MC from frame 1 to frame 2, hence changing the appearance of ALL duplicated MCs.

I have tried a simple action on a button:

on (release) {
tile.gotoAndStop(2);
}

but obviously this only changes one MC - the first one, and none of the duplicated ones.

Please can someone advise about the correct syntax to impact on all duplicated MCs?

Thanks

Jim
