end 

w1, w2, w3 = are defined as weapon id's

a1, a2, a3 = are defined as ammo ( int values )

WARNING: ***:42: Bad argument @ 'giveWeapon' [Expected weapon-type at argument 2, got nil]

* Note : I use the w1, w2, a1, a2 ... some where else in the script, And it works, It don't work when i try to get it from the element data !

k is the key in your loop. That means, it has values 'w1', 'w2' and 'w3' during iterations.The problem is that you try converting these values to numbers. That fails and tonumber function returns nil.

Oh, it's working !
