Hi All.

Im trying to use a computer to control a Enhanced Portals Dialer as seen here. Using the code provided here. http://pastebin.com/AGu2J1Q7

dial = peripheral.wrap("right")
monitor = peripheral.wrap("top")
controller = peripheral.wrap("Portal Controller_0")
portalActive = false
locationCount = 0

function update()
  portalActive = controller.isPortalActive()
  locationCount = dial.getStoredCount()
end

function drawScreen()
  if portalActive then
    monitor.setBackgroundColor(colors.green)
    monitor.clear()
    monW, monH = monitor.getSize()
    monitor.setCursorPos(monW / 2 - string.len("Terminate") / 2, monH / 2)
    monitor.write("Terminate")
  else
    monitor.setBackgroundColor(colors.black) 
    monitor.clear()

    if (locationCount - 1 > 0) then
	  for i = 1, locationCount do
	    monitor.setCursorPos(1, i)
	
	    if (i % 2 == 0) then
		  monitor.setBackgroundColor(colors.gray)
	    else
		  monitor.setBackgroundColor(colors.lightGray)
	    end
  
	    name = dial.getStoredName(i - 1)
	    monW, monH = monitor.getSize()
	
	    monitor.write(name)	 
	    k = string.len(name)
	
	    while (k < monW) do
		  monitor.write(" ")
		  k = k + 1
	    end
	
	  end
    else
	  monitor.setCursorPos(1, 1)
	  monitor.write("No Entries")
    end
  end
end

function handleInput()
  event, side, posX, posY = os.pullEvent("monitor_touch")

  if portalActive then
    dial.terminate()
  else
    if (posY <= locationCount) then
	  dial.dialStored(posY - 1)
    end
  end
end

while true do
  update()
  drawScreen()
  handleInput()
end

Attempting to run the program gives me the following error:

startup:8:Attempt to index ? (a nil value)

I'm assuming this indicates an error on line 8. But I don't know enough to determine what the issue might be. Any help is greatly appreciated.

What was the peripheral name of the portal controller when you activated the wired modem that you attached to it? It would have mentioned it in chat.

Dialing Device_4

Thanks for helping!

So, the third line should be changed to use that name instead of Portal Controller_0, in case you didn't know.
