Transform item on use with 10% chance

[Kubuxxx]

hello!
Today i need script to transform item, but only when im use this item (life crystal - 2177)
on XXXX item, and if its succesful (10% chance ) life crystal transform to item id 9743.

I think it's simple script to write, and i would be thankful to somebody who write it.

Maybe this...:

local i = math.random(1, 10)
function onUse(cid, item, fromPos, itemEx, toPos)
if i == 5 then
doTransformItem(item.uid, 9743)
doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You have obtained a "..getItemNameById(9743)..".")
else
doPlayerSentTextMessage(cid, 18, "Sorry, you fail it.")
end
return true
end

That's the script... Hope you know how to add it to actions

local itemid = 2177
local pos = {x=1000, y=1000, z=7, stackpos=255}
function onUse(cid, item, fromPos, itemEx, toPos)
	local itempos = getThingFromPos(pos)
	if itempos.itemid ~= itemid then
		return true
	end
	local i = math.random(100)
	if (i <= 10) then
		doTransformItem(itempos.uid, 9743)
		doPlayerSendTextMessage(cid, MESSAGE_INFO_DESCR, "You have obtained a "..getItemNameById(9743)..".")
	else
		doRemoveItem(itempos.uid)
		doPlayerSentTextMessage(cid, 18, "Sorry, try again.")
	end
	return false
end
