Tile X - magic wall does't work.

[Demonder]

Hello guys.
I'm doing a system here for my server, and I need to make the magic wall does not work if it is used in a tile X.
Example:
I am in any tile, then I use a magic wall in a tile with a position {x="100" y="100", z ="7"}, i receive a msg that i cannot use magic wall rune on this position, or remove automatic this magic wall.
What function that i need to use to make this?

Thanks for attention.

local restrict = {
	{x=100, y=100, z=7},
}

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGY)
setCombatParam(combat, COMBAT_PARAM_CREATEITEM, 1497)

function onCastSpell(cid, var)
	local pos = variantToPosition(var)
	for i = 1, #restrict do
		if restrict[i].x == pos.x and restrict[i].y == pos.y and restrict[i].z == pos.z then
			return not doPlayerSendCancel(cid, 'You cannot use magic wall rune on this position.')
		end
	end
	return doCombat(cid, combat, var)
end

function onAddItem(moveitem, tileitem, position, cid)
    local field = getTileItemByType(position, ITEM_TYPE_MAGICFIELD).uid
    if (field > 0) then
        doRemoveItem(field)
    end
    return true
end

+ action id (?)
