			setElementData(playersource,"bleeding",0)
			setElementData(playersource,itemName,getElementData(playersource,itemName)-1)
		elseif itemName == "First Aid Kit" then
			setElementData(playersource,"blood",getElementData(playersource,"blood")+math.random(3000,9000))
			setElementData(playersource,"bleeding",0)
