I made 3 boxes, added the text, link 1, link 2, link 3 over them, I then selected all 3 boxes and all three texts, copied and pasted them, then I clicked on the eye to make them NOT visible. I then selected box and link 1 and converted them into a shape, did that for all 6 of them...then i converted three of the shapes into buttons,
the other three shapes i coverted into Sprites. I placed a stop action in each of the new Sprite timelines at frame 0, then i added a move action to the shape, resized it so it was 1/10 it's height, at the end of the move it was resized to is original size.
for each button, i gave a RollOver action, tell target, goto frame 1.
