Bios/Shell Prob [Solved]

I Keep Getting The Error And Don't Know How To Fix It Or How This Happened

ERROR

"bios:257: attempt to call nil
> bios:257: attempt to call nil
Press any key to continue
multishell:64: attempt to call nil"


CODE

"os.pullEvent = os.PullEventRaw
term.clear()
term.setCursorPos(5,2)
print("Password: ")
local input = read("*")
if input == "admin" then
term.clear()
term.setCursorPos(1,1)
shell.run("shell")
else
term.clear()
term.setCursorPos(5,2)
print("Incorrect Password!")
sleep(1.5)
os.reboot()
end"

Change your first line to:

os.pullEvent = os.pullEventRaw

It's pullEventRaw not PullEventRaw.
