Back to previous SCENE script

Hi all!
lets say i have 5 scenes in my fla file, how can i put a <b>“Back Button” </b> in each of the scenes and make it go back to WHICHEVER scene i was at previously?

some actionscripting / javascripting on my button perharps?
a really simple script that will work exactly like:
<A HREF=“javascript:history.go(-1)”> as in in html

Anyone knows? :-\
