Wierd flashing .swf problem

Ok so im trying to make some flashy buttons (using flash! XD) for my school project, and im having a little bit of trouble. Basically I have created the button, and it works fine when I test Movie in Flash, but when I export it, the buttons just flash and dont work. Its hard to explain, so ill attach the .swf and .fla files.

If you can, could you please try and work out what Ive done wrong? Thanks!!!

Oh yeah, and the buttons jsut say “option” right now cos im not sure what text i need to use yet.
