You have the images there, but they're not defined as anything, so that when your javascript calls for LoadCached(this), there isn't any Cached list. That or because the name for your drop down combo box is "cached" and your javscript calles for "Cached". As I said, not that great at debugging javascript, especially when I'm not warmed up. First post too, by the way.

You have a JavaScript error: line 27, unterminated string constant. Looks like you forgot the opening quotation mark in onChange=loadCached(this)".
