You can't target scene names from anywhere else than on the main timeline. So forget about targeting scene names for ever again.
Target a labeled frame instead. Thus label frame 1 of your "Cigs" scene with an unique label, such as cigs1 (no number only labels or at least not starting off with a number, and no special character unless maybe the underscore...), add _root to your path, and target that labeled frame on your button's script...
code:


on (release) {

_root.gotoAndPlay("Gigs1");

}


Works as a charm!
