Ok, because so many people are throwing out ideas about what you have to do to all you're objects to get them to export with your level, I am extremly confused! I linked every object in my level to the reference frame (see the picture below) Is this what I'm supposed to do, or is anything else involved? Man, I am really confused...

make sure they are ATTACHED to your level

Scince I am such a dunbass and a noob at 3ds max, could.. hehe.. someone tell me how to attatch everything together? I have a whole bunch of seperate objects and so when I try to compile the level, I get tons of errors.
