Item Subtype from player slot
 

I dont know if this is something that can fairly easily be solved but i need some help making a script that would scan the item in an item slot (in this case, looking at the offhand slot (17)) and determining what the subtype (i.e. shield, mace, etc) is. Ive tried using the following code, but it doesnt seem to work:

GetItemInfo wants a numeric item id or the string "item:###etc". Which you can get from parsing out the link but the link itself won't work.

This will work:

local _,_,itemID = string.find(GetInventoryItemLink("player",17) or "","item:(%d+)")
local sName, sLink, iQuality, iLevel, sType, sSubType = GetItemInfo(itemID);

Thanks! appriciate it, was having trouble sorting out the string parsing commands.
