Missing col?

I've added a new weapon to FPS and just took the crossbow.cs, copied and changed everything for my new weapon. The problem is for some reason I can not pick up my new weapons and ammo. I know nothing is wrong with my modles, because i'm using the origional crossbow ammo for my new weapon! Along with that the new weapon modle is perfect, I just about took the example crossbow from the starter kit and swaped out the modle in 3dsmax. I can get it to show up in the WB and I can place it aswell. It just will not pick up, while other items still do. I check the log and it just says missing col info. Any ideas?

Edit : Also, when I spwan with my new wepon, it looks correct and all, it just will not fire. Even if I load the ammo. I think this will be fixed tho once I figure out my first problem.
