File size issue w/chained select menu

1) Script Title: Chained Select Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...menu/index.htm

3) Describe problem: I got the chained menu to work from this site just fine but now i'm running into a file size issue. if i exceed 22k in size it gives me a "stack overflow in line 59" error. and if i make it much larger it doesn't even load the selections.
I'm very new to coding anything so a little help would be greatly appreciated. is there some way to link multiple js files of correct size to make this work?

Never mind, found a few type-o's in the config list.
