Error bios:206: [string "startup"]:37: '=' expected

I'm coding a program for a password lock door that has a manual override and a master password that bypasses security so I can fully use the terminal. I have no idea what is wrong. Any attempt to help will be appreciated. Here is my code:

term.clear()
term.setCursorPos(1,1)
os.pullEvent = os.pullEventRaw

password = "1234"
masterpassword = "4321"
manualoverride = "5678"

print("Door Status: Locked")
write "Please Enter Password: "
local input = read("*")

if input == (password) then
print("Password Accepted - Access Granted")
redstone.setOutput("back",true)
sleep(7)
os.shutdown

elseif == (masterpassword) then
print("Processing…")
sleep(1)
print("Terminal Is Now Unlocked")
sleep(2)
print("Welcome Back, JdKnight85")

elseif input = (manualoverride) then
print("Override Accepted")
redstone.setOutput("back",true)

else
print("Password Incorrect")
sleep(2)
print("Rebooting…")
sleep(1)
os.reboot

end





Line 37 is "end". Id on't understand why thats wrong. Aren't you supposed to always put "end"

os.shutdown and os.reboot are functions and should be os.shutdown() and os.reboot()

Thank you, that fixed the first error, but now it is telling me "startup:9: attempt to call nil"

you must have misspelt one of the functions in your actual code. most likely the print command. that error is caused when you try to call something (use as a function) that is not actually a function. example

local myvar='mystring'
myvar('myparam')

would throw the error: "attempt to call string" because myvar is not a function… perhaps you accidentally used prit("Door Status: Locked") or something. the only other thing that could cause this is if you have overwritten a function by accidentally using it as a variable. for example

local oFile=io.open('stored_info','r')
read=oFile:read()
oFile:close()

the above code would work perfectly except that now I have overwritten the read command with whatever is in the file 'stored_info'. it is a mistake I make fairly often actually, just be careful

And your last elseif looks like this:

elseif input = (manualoverride) then[/code
should have two =

ahhhh there we go, can't believe I missed that.nice one remiX

Thank you so much for everything. I used a capital p in print by mistake. everything works fine now. I really appreciate the help.
