AS2 - if statements on buttons

how do i create an if statement for some buttons to say something like:

if button1 is pressed go to frame1
if button2 is pressed go to frame2 etc.

i know i could use button1.onRelease = function(){blah blah;} but i would like to start using if statements and this is a good place to start i guess

any help is appriciated, Cheers Dan
