[solved] Rednet Help.

Hi, I have recently been learning how to use RedNet and I can use it correctly I believe. However, when I try to send a signal from a computer to a turtle to toggle a redstone signal, it doesn't work how I want. At the moment, if I send the signal, the turtle turns the redstone on, but not off after sending it again. However, if I tell the turtle to do it through a program without RedNet, it works perfectly. Here is my code:
Startup:
http://pastebin.com/xm3bpB94

rednet.open("right")
a,b,c = rednet.receive()
if b == "test" then
  shell.run("test")
  print("Running test!")
end

Test:
http://pastebin.com/fs0pgLkz

if rs.getInput("back",true) then
  rs.setOutput("back",false)
else
  rs.setOutput("back",true)
end

I know I don't particularly need to put "test" into it's own program, but I have tried to do it implemented into "startup". Any help in this matter would be greatly appreciated. Many thanks, Tom.

Split into new topic.

As it stands, your startup script accepts one signal, then finishes as it's got nothing left to do. You want it to repeat, yes?

rednet.open("right")
while true do
   a,b,c = rednet.receive()
   if b == "test" then
      shell.run("test")
      print("Running test!")
   end
end

Damn, I knew it would be something as simple as that, I'm pretty sure I tried it before as well. Anyway, thanks for the help, I've got it working now :)/>
