Classes won't load

I am trying to create a Bejewelled type game called BeGemmed. I created the classes for the jewels, but for some reason, Flash doesn’t recognize them when I try to run the file. I get an error message that it can’t find them - although they are in the current directory and are in the library. I was planning on loading the jewels into a TileList Component. Anyway, does anyone have any suggestions.
