Flash noobie ---- rollover script help ! im stuck :(

hi there,

i have a graphic set on a motion guide, what i am after is when a button is rolledover i want it to trigger the tween… basically it is text sliding in from outside the page once a rollover takes place on a button…

i cant figure out the scripting, my tutor did it for me yesterday but i cant remember how,

somthing like,

when a rollover takes place, tell the motion to go from frame 1 to frame 2 ??

any help would be much appreciated !

thanks
