Menu Help

Hey everybody,

I have an FLA that I want to use for a menu I’m making. Currently, the menu is designed for 4 buttons and it has an indicator that slides along under the buttons to show which button the user is on. My menu needs to have 6 buttons. It should be very simple to add 2 more buttons to this piece, but every time add new buttons, the indicator slides way off to the left when I roll over the new buttons I’ve added, instead of sliding under them like it does with the original buttons. I’ve attached the original FLA.

Could anyone tell me how to add new buttons without having this problem? Thanks a lot, I really appreciate the help.
