Managing Multiple External Classes

Hi,

I’m having some trouble getting mulitple external classes to work simultaneously. I have a little game that is running off the document class. I’d like to add a background scroller. I have an external class for the scroller but I don’t know how to make the FLA see this additional AS file. If I make the scroller the doc class, it works fine but of course the game doesn’t work. If the game is the doc class, the scroller doesnt work. I’ve been looking for a good (clear) tutorial on how to manage multiple external classes but have not found anything that tells me the steps how to do it. Can anyone help? Thanks!
