so i was using rednet, and it decided to fail.
i just did a simple rednet.receive(), then it says
lua:1: attempt to call nil

[MKlegoman357]

You probably misspelled it. Check the spelling, Lua is also case-sensitive, so 'rednet' is not the same as, for example, 'RedNet'.

Can we see more code? And make sure the modem is on "rednet.open("side")"

You misspelled receive. You wrote recieve.

Still doesn't work? I assume you've restarted the computer by now.
Could you post screenshots?

1. No, he doesn't need to save the variables
2. You have 2 open parentheses, so that would error.

If you would like the message rednet is sending use this.

rednet.open("left") -- change left to the side of the computer/turtle the modem is on
local senderid, message = rednet.recieve()

Here is an example.

rednet.open("top")
while true do
local senderid, message = rednet.recieve()
print(message)
end
