Click use on ring to place in ring slot

[Nightimarez]

Okay so I made a script that changes a might ring into a death ring. But when you click use on the might ring, it goes into your backpack. I would like for it to go back into the ring slot.
I don't know if it can be done by doTransformItem or CONST_SLOT_RING, but someone please help me.

function onUse(cid, item, frompos, item2, topos)
  	if doPlayerRemoveMoney(cid, 500000) == TRUE then
doSendMagicEffect(getPlayerPosition(cid), CONST_ME_FIREAREA);
		doRemoveItem(item.uid,1)
  		doPlayerAddItem(cid,6300,1)
  else 
            doPlayerSendCancel(cid, 'You need 50 Crystal coins.') 
            doSendMagicEffect(getPlayerPosition(cid), CONST_ME_POFF) 
        end 
        end

Edit, nvm guys.. got it working.

function onUse(cid, item, frompos, item2, topos)
	local value = 6301
  	if doPlayerRemoveMoney(cid, 500000) == TRUE then
doSendMagicEffect(getPlayerPosition(cid), CONST_ME_FIREAREA);
	doTransformItem(item.uid, value)
  else 
            doPlayerSendCancel(cid, 'You need 50 Crystal coins.') 
            doSendMagicEffect(getPlayerPosition(cid), CONST_ME_POFF) 
        end 
        end

If you're using The Forgotten Server 0.3.7 (or later):

doPlayerAddItem(cid, itemid, 1, false, CONST_SLOT_LAST)
