I have what my be a simple question. I've put together a simple navbar that loads a movie clip with more buttons in it. When I click on the button, the right movie clip plays, but if I click on it again, it plays a wrong movieclip. You can see what I am talking about at: www.mnr-sales.com/flash (try clicking on the same button twice, you'll see what I mean, it loads a different subnav)
I see what you mean, its hard to tell what the problem is just by looking at the finished product. Could be you have a few clips with the same name, to it gets confused and plays the wrong one...
I would look over your button actions and maybe post an example here if you dont see a problem with it.
Your problem is simple: there is a gotoAndPlay action instead of a gotoAndStop. Do this: modify all your buttons (Home, Advertise, Search, Prices, Support) to a gotoAndStop(#) action and everything will work as you expect it.
