[Help] 3 levers to make a ladder

[Spoking]

Hello,

I can't figure out why my script is not working, so if there is anyone here that knows, please post.

local ladderpos = {x=1000, y=1000, z=7}

function onUse(cid, item, fromPosition, itemEx, toPosition)
	local a, b, c = 
		getTileItemById({x=999, y=999, z=7}, 1946).uid,
		getTileItemById({x=1000, y=999, z=7}, 1946).uid,
		getTileItemById({x=1001, y=999, z=7}, 1946).uid
		
	if item.itemid == 1945 then
		doTransformItem(item.uid,item.itemid+1)
			if 0<a and 0<b and 0<c then
			local v = getTileItemById(ladderpos, 1386).uid
				if v < 1 then
				doCreateItem(1386, 1, ladderpos)
				
				end
			end
	
	
	elseif item.itemid == 1946 then
		local v = getTileItemById(ladderpos, 1386).uid
		doTransformItem(item.uid,item.itemid-1)
			if 0>a or 0>b or 0>c and v>0 then
			doRemoveItem(v)
			end
	end
	
end

You have to pull 3 switches, and once that is done, a ladder appears.
If the switches aren't ID 1946, remove the ladder if there is a ladder.

local ladderPos = {x = 1000, y = 1000, z = 7}
local t = {
        getTileItemById({x = 999, y = 999, z = 7}, 1946),
        getTileItemById({x = 999, y = 999, z = 7}, 1946),
        getTileItemById({x = 999, y = 999, z = 7}, 1946),
        getTileItemById(ladderpos, 1386)
        }

function onUse(cid, item, fromPosition, itemEx, toPosition)
    local get = t[1], t[2], t[3]
    local l = t[4]
    if get then
        doCreateItem(1386, 1, ladderPos)
    end
    if not t[1] or not t[2] or not t[3] then
        if l then
            doRemoveItem(getThingPos(ladderPos).uid, 1)
        end
    end
    return TRUE
end
