So, I have this code already (I am trying to make my own chat program) but for some reason, the rednet.send() on line 26 won't work, because it requires a number. I thought I could do this by using tonumber(), but it doesn't work.
I would be very pleased if you could tell me how I can do this.
Thanks in advance

To use rednet.send, you need to provide two arguments, the channel and the message. All computers listening to that channel can receive the message. Here's an example:

id = 29
msg = "Hello, Computer #"..id
rednet.send(id, msg)

I believe you mean

rednet.send(id, msg)

Yes, but the string from the arguments used in chat <ID> where <ID> is the argument, should be converted in to an int, but it wont!

Lua is one-indexed, not zero-indexed. Change line 26 to use both tonumber and the correct indexing:

rednet.send(tonumber(chatID[1]), "authentication!!!!")

Aha, thank you very very much Lyqyd
