I'm trying to get some local boolean variables working., but it's giving me an error,

Here's the code:

term.clear()
term.setCursorPos(1,1)
print("Scanning peripherals...")
if peripheral.isPresent("left") then
if peripheral.getType("left") == "monitor" then
  local monitorcheck = true
  monitor = peripheral.wrap("left")
elseif peripheral.getType("left") == "modem" then
  local modemcheck = true
  modem = peripheral.wrap("left")
end
end
if peripheral.isPresent("top") then
if peripheral.getType("top") -- "monitor" then
  local monitorcheck = true
  monitor = peripheral.wrap("top")
elseif peripheral.getType("top") == "modem" then
  local modemcheck = true
  modem = peripheral.wrap("top")
end
end
if monitorcheck == true then
print("Attaching monitor...")
sleep(0.4)
end
if modemcheck == true then
print("Attaching modem...")
sleep(0.4)
end
print("Setting up login process...")
sleep(0.4)
term.clear()
term.setCursorPos(1,1)
shell.run("disk/password")
shell.run("disk/login")

When I start up the computer (It's a startup program), I get the following:

CraftOS 1.4
bios:206: [string "startup"]:15: 'then' expected

I'm very new to programming, and through some Google searching I didn't seem to find anything (Maybe I just didn't look hard enough). Adding 'then' to the end of the mentioned line still gives the same error. Trying to use a global variable instead doesn't affect it either. I'm sure it's a very amateur mistake.

You commented out you then, on the line immediately prior. I guess you wanted:

if peripheral.getType("top") == "monitor" then

But you replaced the "==" with "--"

Oh wow, I feel like an idiot now. Thanks for pointing that out.

For longer programs you should use some kind of editor that gives you highlighting for Lua, most people probably use Notepad++. That makes spotting these kinds of things a lot easier.
