Rednet:39 Number Expected

Hello. I am working on a rednet relaying server for my new minecraft house and I am getting an error.

Here's my code, more explained later in the post:

local req_id, req_message = rednet.receive(5);
  if (req_message ~= nil) then
    where,cmd = req_message:match("([^,]+),([^,]+)");
    rednet.send(where, cmd, true);

A rednet message is sent into the server with something like this:
"10,command"
ID,CMD

I get the error:
rednet:39: Expected number

But there's a print straight after it, and when I comment out the send function, the print says:

print("Sent " .. cmd .. " to " .. where);

100% correctly, with the ID as it should be, and the command.

The definition for rednet.send is as follows

rednet.send(number receiverID, string message)

So that true at the end wouldn't do anything. Anyways, im guessing the problem is your where variable is a string. Give this a try

local req_id, req_message = rednet.receive(5);
  if (req_message ~= nil) then
	where,cmd = req_message:match("([^,]+),([^,]+)");
	rednet.send(tonumber(where), cmd);
