for the simple door w/out the anti hacking stuff, i followed the instructions and entered the code/ saved it and all that good stuff. then i exited the computer and went back in. there was no "enter your password" on the screen and when i typed it in anyway it said

>beardedpineapple -- my password >password accepted >beardedpineapple:2: attempt to index? ( a nil value)

anybody know what this means? (i just started with computercraft)
