Quick question...!

Hi guys,
I am embarrassed I am having to ask such a seemably easy question but for some reason, my Flash is being a brat today.
I have a mc on the main timeline called black_mc
inside of that I have a btn called boars_btn
so on my main timeline actions i have:

black_mc.boars_btn.onRelease = function(){
trace("horrible flash");
}

to call the btn, but nothing happens. WHYYY? According to other tutorials I seem to be referencing it right?

Thanks in advance to any responses.
