collision with a property?

ok im trying to hav my player collide with a ammo clip and the gun’s ammo (value) go up either +100 or back to 500. but it wont work. i gave the player, the gun, and the ammo properties and set up wut i think is the correct logic bricks. here is the file: http://files.filefront.com/fpsgameblend/;11035474;/fileinfo.html

Hello
the player object (“hero”), should have a property named “hkamo” and not the gun?!
Bye

thanks also, i imported a .x model into my game and not only will the actions not work but also it keeps appearing upside down. do u need me to upload a updated version of my project or do u hav a solution?
