Bazir Tapestry script (poi seal)

[Xavicrak]

Hello there. I am trying to make a simply script. Let me explain: As you know, in Bazir seal of POI there is a blue tapestry which is on the mirror teleport.

The script simply must move this tapestry to next south position.

this is the error i get in console:

[Error - Action Interface ]
data/actions/scripts/PitsOfInferno/BazirTApestry.lua:OnUse
<luaDoRemoveItem> Item not found

function onUse(cid, item, frompos, item2, topos)
if item.uid == 65534 then
if item.itemid == 1871 then

local TapestryPos = {x=400,y=1522,z=13, stackpos = 1}
local Tapestry = getThingFromPos(TapestryPos)

local NewTapestryPos = {x=400,y=1523,z=13, stackpos = 1}

	doRemoveItem(Tapestry)
        doCreateItem(1871,NewTapestryPos)

end
end
return 1
end
