Weapons crate woes!!

[BajtMe]

I am trying to add some weapon and medicine crates to my game, but as usual, i have no idea what i'm doing.
I have managed to get them in to the game, and they appear to be working, sort of, but on reload i get a bunch of error messages i dont understand.
I was hoping someone could help me out with a "for dummies" translation and possibly a solution.

Pics of the error messages and def file attached.

There you go. It was too long to use the insert code thingie so i attached the file

Had a good long look in there and now i am even more confused. It's becoming painfully clear i should just stick to textures.

do not add digits to the end of def names, this cause loading and saving errors.

That did the trick. Everything is working fine now, so far at least.
Thank you very much for your help.
