Simple button code....cant figure it out

1

ok so all i want to do is have a simple button blinking back n forth, on rollover, it stops blinking, and on roll out, it starts again

i put this in

stop();

invizBtn.addEventListener(MouseEvent.ROLL_OVER,playit);
function playit(e:Event):void
{
plusBtn.gotoAndStop(“start”);
}

invizBtn.addEventListener(MouseEvent.ROLL_OUT,lolz2);
function lolz2(e:Event):void
{
plusBtn.play();
}

i tried rollOver etc…

and it doesnt work…im sure its stupid but hmmm im still learning this PAIN as3!

edit* on top where it says “playit” theres no space in the word…for some reason i cant seem to remove it…

but yeah, any ideas? thanks in advance
