Little quest problem

[Darqneez]

Hello, I need a script for levers.

Description
1 to 3 black numbers, are numbers of levers
1 to 3 red numbers, are numbers of stones that should appear
1 to 3 green number, are numbers of stones that should disappear

I have written a script some hours ago but it doesnt work
I want script to do 1 thing. I know I need 3 such a scripts, but when I have the first one, I will know how to build two others. What should the script do? When using lever number 1 it should make stones with red number 1 appear and stone with green number 1 disappear. if Lever is used it should do it vice versa. Here's my not working script, maybe some rework would help. Please help me fast

local gatepos1 = {x=2130, y=1881, z=14, stackpos=1}
local gatepos2 = {x=2121, y=1873, z=14, stackpos=1}
local gatepos3 = {x=2113, y=1881, z=14, stackpos=1}
local gatepos4 = {x=2121, y=1888, z=14, stackpos=1}

function onUse(cid, item, frompos, item2, topos)
local getgate1 = getThingfromPos(gatepos1)
local getgate2 = getThingfromPos(gatepos2)
local getgate3 = getThingfromPos(gatepos3)
local getgate4 = getThingfromPos(gatepos3)

	if item.itemid == 1945 and getgate1.itemid == 0 then
		doCreateItem(getgate1.uid, 1)
		doTransformItem(item.uid, item.itemid+1)
	elseif item.itemid == 1946 and getgate1.itemid == 1304 then
		doRemoveItem(1304, 1, gatepos1)
		doTransformItem(item.uid, item.itemid-1)
	else
		doPlayerSendCancel(cid,"Sorry, not possible.")
	end

	if item.itemid == 1945 and getgate2.itemid == 0 then
		doCreateItem(getgate2.uid, 1)
		doTransformItem(item.uid, item.itemid+1)
	elseif item.itemid == 1946 and getgate2.itemid == 1304 then
		doRemoveItem(1304, 1, gatepos2)
		doTransformItem(item.uid, item.itemid-1)
	else
		doPlayerSendCancel(cid,"Sorry, not possible.")
	end

	if item.itemid == 1945 and getgate3.itemid == 0 then
		doCreateItem(getgate3.uid, 1)
		doTransformItem(item.uid, item.itemid+1)
	elseif item.itemid == 1946 and getgate3.itemid == 1304 then
		doRemoveItem(1304, 1, gatepos3)
		doTransformItem(item.uid, item.itemid-1)
	else
		doPlayerSendCancel(cid,"Sorry, not possible.")
	end

	if item.itemid == 1945 and getgate4.itemid == 1304 then
		doRemoveItem(getgate4.uid, 1)
		doTransformItem(item.uid, item.itemid+1)
	elseif item.itemid == 1946 and getgate4.itemid == 0 then
		doCreateItem(1304, 1, gatepos4)
		doTransformItem(item.uid, item.itemid-1)
	else
		doPlayerSendCancel(cid,"Sorry, not possible.")
	end
return 1
end
