How Do I Change my Crystal coin's, to gold nuggets.. i know its a noob question for a "professional" but im new with scripting and im learning slowly and this could realy help so please give me the answer??...

 

[Ferchox]

function onUse(cid, item, fromPosition, itemEx, toPosition)
if item.itemid == ITEM_CRYSTAL_COIN and item.type == ITEMCOUNT_MAX then
doChangeTypeItem(item.uid, item.type - item.type)
doPlayerAddItem(cid, IDOFNUGGETS, 1)
doSendAnimatedText(fromPosition, "",TEXTCOLOR_LIGHTBLUE)
end
end

think that should would work, but the nuggets will appear if they have 100 crystal coins

P.S: Remember to add the id of nuggets where i did Bold text
