在if语句中使用computercraft变量

我有一个小问题，我是Lua和ComputerCraft的新手。所以我的问题我认为是因为我太蠢了，在if语句中编写变量更改。我会贴出我的代码希望你们可以帮我解决这个问题。谢谢

mon = peripheral.wrap("top")
modem = peripheral.wrap("right")
mon.clear()
mon.setCursorPos(1,2)
mon.blit("粉碎机","0000000000","dddddddddd")
redstone.setOutput("right", true)
Pulverizer = true
mon.setCursorPos(1,4)
mon.write("熔炉","0000000","ddddddd")
redstone.setOutput("left", true)
local Furnice = true
mon.setCursorPos(1,6)
mon.write("注液室","00000000000000000","ddddddddddddddddd")
local Injection_Chamber = true
redstone.setOutput("top",true)
mon.setCursorPos(1,8)
mon.write("冶金模拟熔炉","000000000000000000","dddddddddddddddddd")
local Metalurgig_InFuser = true
redstone.setOutput("bottom", true)
while true do
  event,side,x,y = os.pullEvent("monitor_touch")

  if x > 1 and x < 11 and y == 2 and Pulverizer == true then
    mon.setCursorPos(1,2)
    mon.clearLine()
    mon.blit("粉碎机","0000000000","eeeeeeeeee")
    redstone.setOutput("right", false)
    Pulverizer = false

 elseif x > 1 and x < 11 and y == 2 and Pulverizer == false then
   mon.setCoursorPos(1,2)
   mon.clearLine()
   mon.blit("粉碎机","0000000000","dddddddddd")
   redstone.setOutput("right", true)
   Pulverizer = true
  end
end

这是代码的Pastebin链接：[代码链接] (https://pastebin.com/06WmfbjJ)

所以问题出在代码的这一部分

if x > 1 and x < 11 and y == 2 and Pulverizer == true then
mon.setCursorPos(1,2)
mon.clearLine()
mon.blit("粉碎机","0000000000","eeeeeeeeee")
redstone.setOutput("right", false)
Pulverizer = false

粉碎机变量不想从true变成false，所以这段代码现在无法启动

   elseif x > 1 and x < 11 and y == 2 and Pulverizer == false then
   mon.setCoursorPos(1,2)
   mon.clearLine()
   mon.blit("粉碎机","0000000000","dddddddddd")
   redstone.setOutput("right", true)
   Pulverizer = true

我不知道为什么 这是一个游戏内视频链接，所以你们可以看到在视频中它变成了红色，但不再变成绿色
