Computercraft Error Help!

[FIsh_tacoz]

Ok, I would usually go to the computercraft forums, but apparently I can't post any topics. Anyways, I was getting an error I couldn't understand how to fix. Here is my code:

mon.peripheral.wrap("right")

mon.setCursorPos(1,2)

mon.write("Test")

event, e=os.pullEvent("key")

print"Test text"

while true do

if e==25 then

shell.run("lock") -- this is a password program I have set up

break

end

end

Anyways, what this program does is basically writes something on my monitor, and when P is pressed, it runs a password system. However, after about 10 seconds, an error comes up: nil: vm error: java.lang.NullPointerException

I have no idea what this means, or what is causing it XD

any help would be appreciated. Thanks

mon = peripheral.wrap("right")

print("Test text")

("Test Text"

mon = peripheral.wrap("right")

print("Test text")

I added the mon.write("test"). is that not the same? Or am I missing something? Oh, and the mon.peripheral thing was a typo :/

("Test Text" I added the mon.write("test"). is that not the same? Or am I missing something?

I was correcting your syntax.

print"Test text"

^this is not correct.

Hm

I was correcting your syntax.

print"Test text"

^this is not correct.

Err, still gives me the error

Could it be in the lock program?

Could it be in the lock program?

Well, the lock program works when I isolate it to itself. Also, I haven't even pressed the event key P to launch the Lock program, so I don't think the lock would be a problem. My sign just flashes off, then when I open the computer, that error comes up(after I type startup or reboot).
