Button States with a Movie Clip - HELP!

Now I’m as loving of Flash as the rest of you, however I just haven’t been at it as long. So if any of you have a moment to give an Aussie a hand with this file, it would be wonderful.

Problem is:
Making a navbar which shows/hides on rollover. Within the navbar movieclip are various buttons, with rollover states. At the symbol level, everything is dandy, but within the navbar movieclip the buttons don’t seem to be recognised, meaning the rollover states don’t work and I presume means I won’t get a result when I get to making them load new movies.

File is here:
