Please help password code not working!

Hi! I made a code for a password protected computer. The password part works but when i type it in the screen just goes blank.
Here is the code:
os.pullEvent = os.pullEventRaw
while true do
term.clear()
term.setCursorPos(1, 1)
print("CreeperCity Computer Security")
write("Password: ")
if read("*") == "2007" then
print("Access Granted")
sleep(2)
term.clear()
term.setCursorPos(1, 1)
break
else
print ("Incorrect Password")
sleep(1)
end
end
os.pullEvent = oldPull

Firstly, you should get into the habit of using CODE tags when inserting code, makes it easier to read.

os.pullEvent = os.pullEventRaw
while true do
    term.clear()
    term.setCursorPos(1, 1)
    print("CreeperCity Computer Security")
    write("Password: ")
    if read("*") == "2007" then
        print("Access Granted")
        sleep(2)
        term.clear()
        term.setCursorPos(1, 1)
        break
    else
        print ("Incorrect Password")
        sleep(1)
    end
end
os.pullEvent = oldPull

Where are you defining oldPull? It should be `local oldPull = os.pullEvent` on the first line, before you override it.

My guess is you are setting pullEvent to nil, and then ComputerCraft is completely crashing when the main shell tries to yield.

I think you're right. Just add at the top of the code

 oldPull=os.pullEvent

It works now thanks!
