Rednet not working?

I have a turtle perma-mining with this code:

while true do
  os.queueEvent("randomEvent")
  os.pullEvent()
  i = 1
  shell.run("excavate","20")
  shell.run("turn","right","2")
  shell.run("go","up","1")
  shell.run("go","forward","5")
  rednet.broadcast("Mining Turtle Excavating Session Complete")
  slot = 1
  while slot < 10 do
	turtle.select(slot)
	turtle.drop()
	slot = slot + 1
  end
  shell.run("turn","right","2")
  shell.run("go","forward","5")
  shell.run("go","down","1")
end

and my receiving computer running:

while true do
  senderID, message, distance = rednet.receive()
  mon = peripheral.wrap("left")
  mon.print(message)
  mon.print("ID & distance: ")
  mon.write(senderID)
  mon.write(", ")
  mon.write(distance)
  while s < 5 do
	rs.setInput("bottom",true)
	sleep(0.3)
	rs.setInput("bottom",false)
	sleep(0.1)
	s = s + 1
  end
end

but nothing happens when I broadcast the message, be it automatically by the turtle's code or with a command, so the receiver just hangs permanently. What am I doing wrong? The turtle is wireless and the receiver console has a modem, and the distance is short. I tried with rednet.send too and also pullEvent.

Have you made sure to call rednet.open("side"), changing side to the side of the modem, before attempting to send or receive messages via rednet?

I have fixed your receiver. you will need to add a rednet.open("right") to the turtle script or ti will not be able to broadcast.

Spoiler

rednet.open("top") --  you have to turn on wifi for it to work.
mon = peripheral.wrap("left")
term.redirect(mon)
while true do
  senderID, message, distance = rednet.receive()
  print(message)
  print("ID & distance: ")
  write(senderID)
  write(", ")
  print(distance)
  for i = 1,5 do
		rs.setOutput("bottom",true)
		sleep(0.3)
		rs.setOutput("bottom",false)
		sleep(0.1)
  end
end

you can use the wifi section of this to test that it is working
