the code for the function to get durability as well as the tooltip function thats supposed to display the repair cost...

-- Durability Frame --

local myTip = nil

	pEquipDura = { min=0, max=0};

	if not tmpTip then tmpTip = CreateFrame("GameTooltip", "GUITT") end
	equipCost = 0
	for _, slotName in ipairs(slots) do
		local item = _G["Character" .. slotName]
		local hasItem, _, repairCost = tmpTip:SetInventoryItem("player", item:GetID())
		local Minimum, Maximum = GetInventoryItemDurability(item:GetID())
		if hasItem and repairCost and repairCost > 0 then
			equipCost = equipCost + repairCost
		end
		if Minimum and Maximum then
			pEquipDura.min = pEquipDura.min + Minimum
			pEquipDura.max = pEquipDura.max + Maximum
		end
	end
	bagCost = 0
	for bag = 0, 4 do
		for slot = 1, GetContainerNumSlots(bag) do
			local hasCooldown, repairCost = tmpTip:SetBagItem(bag, slot)
			local Minimum, Maximum = GetContainerItemDurability(bag, slot)
			if repairCost and repairCost > 0 then
				bagCost = bagCost + repairCost
			end
			if Minimum and Maximum then
				pBagDura.min = pBagDura.min + Minimum
				pBagDura.max = pBagDura.max + Maximum
			end
		end
	end
	if bagCost < 0 then bagCost = 0 end
	totalCost = equipCost + bagCost
end
