The reason why you are getting the error is that he dident define UID as u can see.
doPlayerAddItem(uid, itemid, <optional> count/subtype)


Try this

Code: 
		    doPlayerGiveItem(cid, itemid, charges)


as u can see i removed the count.. Altought it dosen't matter since it automaticly says it's 1 =)
