Turns out it was the computers in tutorial, I had to destroy them and reprogram them to get it to work but then I had no problems. When I looked at my own computer tests I spelled something wrong (I am horrible at spelling)
If I type programs it shows them in the list but trying to do anything else with them doesn't work. I might have installed it wrong but the only difference is that my computercraft is in a Zip file while the instructions show it in a folder so I don't know why isn't working.
It still says program not found if I type in, for example, shell.run ("ElevatorControlMotor") and if I reboot the computer it loses that rednet.open command so I have to retype it every time it reboots.
Ok I am trying to get this program working in computer craft but when I open up a computer in the example world or a computer I tried to make I get a message that says:
Settings loaded
rednet:57: No open sides
Command: (The cursor is under the C)
If I try to type in a command it just says: program not found
What am I doing wrong?
