[error] password script trouble ->[string "startup"]:10: ')' expected

So i'm trying to create a door password script (see below)

function lock()
term.clear()
term.setCursorPos(1,1)
os.PullEvent = os.pullEventRaw
pass = oi.read()
if pass == "test" then
term.clear()
redstone.setOutput("right", true)
sleep(3)
redstone.setOutput("right", false)
lock()
else
lock()
end
end
lock()

it is saved to disk/startup

I get an error saying that in line 10, there's a ')' missing when first putting in the floppy then activating the computer, but based on this video it looks fine to me. [media]http://www.youtube.com/watch?v=dp-adiB2aaY[/media]

I'm very new to this, so if there's an obvious problem, lemme now. Thanks :)/>/>

This should work.

function lock()
term.clear()
term.setCursorPos(1,1)
os.PullEvent = os.pullEventRaw
pass = io.read()                                   --Edit happned here, it is supposed to be io.read() not oi.read()
if pass == "test" then
term.clear()
redstone.setOutput("right", true)
sleep(3)
redstone.setOutput("right", false)
lock()
else
lock()
end
end
lock()

This is my pw lock, put this on the right side of the door you want to open

os.pullEvent = os.pullEventRaw
pass = "password" --Change you're pw here
print("Password lock!")
write "Password: "
input = read()
if input == pass then
print("Accsess granted!")
rs.setOutput ("right",true)
sleep(5)
os.shutdown()
else
print ("Wrong password!")
sleep(3)
os.shutdown()
end

Thanks! Dumb mistake as I thought!
