Sub menu buttons not linking

Hello everyone;

I have an fla, 4 scenes. scene one is home. I have a movie on the stage that has several layers, first is actions, with stop on the first frame. I also have a button that has a rollover action to go to frame two where the sub menu buttons appear. I also have invisible buttons to close the sub menus by going to frame one. Everything is working great except for this. What I want is that when the user clicks on the sub menu button, it takes him to scene2. That is not happening, I have checked on the spelling of the scene names and everything. What is actually happening when the sub menu button is clicked, all the sub menu buttons dissappear instead. I also tried creating several new files and do the same thing with no solution.
Please see attached FLA.

Can anyone help plz.
Thanks
Raffi
