Arrays 一个函数和一个数组，声明id，空变量？

从昨天开始，我对函数和数组有一个问题。似乎杠杆ID没有声明或其他什么

这是我的密码：

function tpp(leverID, from, to)

if item.uid == leverID and item.itemid == 1945 then

    local count_players = #to
    local store = {}

    for i = 1, count_players do
        local pid = getTopCreature(from[i]).uid
        if (pid == 0 or not isPlayer(pid)) then
                return doPlayerSendCancel(cid, 'You need ' .. count_players .. ' players to use this lever.')
        end
        store[i] = pid
    end

    for i = 1, count_players do
        doSendMagicEffect(from[i], CONST_ME_POFF)
        doTeleportThing(store[i], to[i], false)
        doSendMagicEffect(to[i], CONST_ME_TELEPORT)
    end

    doTransformItem(item.uid, item.itemid + 1)

elseif item.uid == leverID and item.itemid == 1946 then
    doTransformItem(item.uid, item.itemid -1)
end

end




function onUse(cid, item, fromPosition, itemEx, toPosition)


local pos = {
    ['pos_start'] = {
            {['x'] = 1059, ['y'] = 1034, ['z'] = 7},
            {['x'] = 1060, ['y'] = 1034, ['z'] = 7}
    },
    ['pos_end'] = {
            {['x'] = 1059, ['y'] = 1032, ['z'] = 7},
            {['x'] = 1060, ['y'] = 1032, ['z'] = 7}
    }
}

tpp(10150, pos['pos_start'], pos['pos_end'])

return true


end

我得到了这个错误的答案：

尝试索引全局“项”（零值）

我是卢阿的新手。有人能帮我吗？谢谢

当您从onUse（）函数调用时，可能忘记了将'item'变量传递给tpp（）函数

由于tpp（）函数的作用域或其参数中并没有“item”变量，所以该变量被认为是全局变量，并且并没有具有该名称的全局变量
