movie clip else statement

I have 2 movie clip scripts below which on rollover another movie clip is affected.
In this case "buttonsupporters".

how do I combine these two scripts into the one rollover function?

on (rollOver) {
   if (_root.buttonsupporters._currentframe ==1) {
   _root.buttonsupporters.gotoAndPlay(2);
} else {
   _root.buttonsupporters.gotoAndStop;
}
}

on (rollOver) {
   if (_root.buttonwork._currentframe ==1) {
   _root.buttonwork.gotoAndPlay(2);
} else {
   _root.buttonwork.gotoAndStop;
}
}
