Simple Lock Program bios:206: [string "lock"] :9: '=' expected

Hello
I just started learning to work with computer craft and LUA script today.
I have previous experience with several scripts and stuff but I was working on this simple program to retract some sticky pistons using a password system. When I try to run the program I get an error that says bios:206: [string "lock"] :9: '=' expected and I dont have the slightest clue what this means. The word lock is no where in the script so i thought id change the program name to 'password' and then i got bios:206: [string "password"] :9: '=' expected.

I just need assistance knowing what the problem is.



Pass=cowfence
write "Good Day, Mason!"
write "Please enter the password"
input=read()
if
input==pass
then
term.clear
term.setcursorpos(1,1)
print "Access Granted…!"
rs.setoutput("Back,True")
os.shutdown
else
term.clear
term.setcursorpos(1,1)
Write "PASSWORD INCORRECT"
Sleep(2)
term.clear
term.sercursorpos(1,1)
Write "Shutting down…
Sleep (2)
os.shutdown
end

Pass=cowfence
write "Good Day, Mason!"
write "Please enter the password"
input=read()
if input==pass then
term.clear()
term.setcursorpos(1,1)
print "Access Granted…!"
rs.setoutput("back", true )
os.shutdown()
else
term.clear()
term.setcursorpos(1,1)
write "PASSWORD INCORRECT"
sleep(2)
term.clear()
term.sercursorpos(1,1)
write "Shutting down…"
sleep (2)
os.shutdown()
end

you need to use lower case and put () on the end of term. and os. and it says string lock because the program is called lock

thanks i didnt know () was a requirement

Also, the 9 in the error message indicates the error occurred on line 9 of your program. In this case, term.setcursorpos(1,1) should be written as term.setCursorPos(1,1).

oh yeh can't believe I missed that…

Besides the above corrections, the following should also be corrected:

Pass=cowfence
should really be:
Pass = "cowfence"

Lua is case sensitive, so things like:

term.setcursorpos(1,1)
rs.setoutput("Back", true)

Are wrong, they should be:

term.setCursorPos(1, 1)
rs.setOutput("back", true)

Fixed code:

local pass = "cowfence" -- needs quotes to be a string
write("Good Day, Mason!")
write("Please enter the password")
local input = read()
if input == pass then
  term.clear()
  term.setCursorPos(1,1)
  print("Access Granted...!")
  rs.setOutput("back", true) -- true shouldn't be a string, no quotes there. And "Back" is not a valid side, "back" is.
  os.shutdown()
else
  term.clear()
  term.setCursorPos(1, 1) -- setcursorpos is wrong, it's setCursorPos
  write("PASSWORD INCORRECT") -- write, not Write
  sleep(2)
  term.clear()
  term.setCursorPos(1, 1)
  write("Shutting down...")
  sleep(2)
  os.shutdown()
end
