Creating hit button rollover

Hi as you may know im new here so I dont know whether or not I am posting in the right place for something I need help with which is to make a hit button rollover.

Anyways I want to make a hit button rollover from the picture provided below so that when I click on one of the links on the menu (in picture below) lets say contact us. When I hit that I want a guitar to come up from below the menu which I have done by using tweening.

Before I did any of that I made one of the links in that menu a button symbol (converted to) then i selected the hit frames from the options that were available and i converted it to movie clip symbol.

So am I doing any of this right for me to get it to do what i want it to do?

Would really appreciate help lots as I need this to be done asap but I wont go into that…

Thanks in advance

P.S. i can also send the flash file if any of you would like to look at what im trying to do with it and get a better idea
