Okay. I'm making a program here. It uses the modem api to send messages.
Currently, I'm implementing a command that allows users to change their channel.
But, I get the error "Expected number" on line 108. I can't for my life figure out why.
Thanks for help.

Line 47:


      channel = tonumber(args[1])

If args[ 1 ] was not a number, channel is now nil, resulting in you passing nil, nil to modem.transmit on line 108.

Suggested Fix: Change line 47


      channel = tonumber(args[1]) or channel
