ActionScript 2.0 :: Communication - Controlling The Appearance Of A Radio Button After It's Selected

I've got a relatively simple problem with controlling the appearance of a radio button after it's selected. I'm using Flash CS5.5 and AS2. I've got a radio button set up as a two-frame mc, the first frame labeled "on", the second "off". When put on the stage with this code on it, it functions properly:

onClipEvent (load) {
answer = false;
}

Whenever I add additional code to the radio button mc (in this instance, telling an invisible mc in the same frame to gotoAndStop (2)), the radio button stops changing appearance. I've been using the syntax

on (press) {
tellTarget ("_root.OtherMC.OtherMC_2") {
gotoAndStop (2);
