我一直得到一个预期的错误，当我有字符串

我不断收到第61行的预期错误，我无法找到问题的任何想法？我试图努力出来，并重新安排其即时通讯使用电脑工艺periherals MAG读卡器，并试图MAG卡门我一直得到一个预期的错误，当我有字符串

你能发表评论@第61行，以便我们可以看到错误发生在哪里？ thx – Thomas

我改变了它在行尾有注释的地方 –

我认为你必须用SHA.SHA1_2（komata）替换SHA，SHA1_2 – Thomas

你错过拼写为“调制解调器”与MODEN上2行。

if moden == nil then

也..

if moden.isPresentRemote("mag card reader_0") then

至于错误。

if SHA,SHA1_2(p1) == cards[x] then --line 61 is right here

我相信..应该是这样..

if SHA.SHA1_2(p1) == cards[x] then --line 61 is right here

调换,为.应该做的伎俩。
