I use this to auto repair my gear when visiting a vendor. But when using a repair bot and having guild bank repair enabled, it ignores it and repair using my own money, could anyone tell me how to modify it to repair through the guild bank funds in priority over mine please ?

local function CostString( cost )
 local gold = abs(cost / 10000)
 local silver = abs(mod(cost / 100, 100))
 local copper = abs(mod(cost, 100))
 
 if cost > 10000 then
  return string.format( "|cffffffff%d|r|cffffd700g|r |cffffffff%d|r|cffc7c7cfs|r |cffffffff%d|r|cffeda55fc|r", gold, silver, copper)
 elseif cost > 100 then
  return string.format( "|cffffffff%d|r|cffc7c7cfs|r |cffffffff%d|r|cffeda55fc|r", silver, copper) 
 else 
  return string.format("|cffffffff%d|r|cffeda55fc|r", copper )
 end
end
local function print(msg)
 DEFAULT_CHAT_FRAME:AddMessage(msg)
end
local f = CreateFrame("Frame", nil, UIParent)
f:RegisterEvent("MERCHANT_SHOW")
f:SetScript("OnEvent", function()
 if CanMerchantRepair() then
  local cost = GetRepairAllCost()
  local money = GetMoney()
  if money < cost then
   print( string.format("Autorepair failed, you need %s more.", CostString( cost - money )) )
  elseif cost > 0 then
   RepairAllItems()
   PlaySound("ITEM_REPAIR")
   print( string.format("Autorepaired for %s.", CostString( cost )) )
  end
 end
end)

I believe you just pass the value 1 to RepairAllItems to use guild funds.

By the way, you can remove your CostString function and use the new API: GetCoinTextureString( amount, fontHeight ). http://forums.worldofwarcraft.com/thread.html?topicId=10043170854&pageNo=1&sid=1#5

Be warned that if the money in the Guild bank isn't sufficient it will still pull from your own funds.
