Need Offline Training Refiller!

[GM Drama]

I would like players being able to refill their offline training bar to 100% by using an item.
I don't like giving people more work but it would be very nice if you could send me a script for it!

offlinerefill.lua

function onUse(cid, item, frompos, item2, topos)
	doCreatureSetStorage(cid, 62666, 720)
end

actions.xml

<action itemid="ID" event="script" value="offlinerefill.lua"/>

Not sure if this works. Looks too easy but it should work.
