[Lua][Question]

I'm making a simple program that's going to be part of a larger "mother" program. This bit is just the part that's suppose to receive rednet messages but i can't get it to work right.

print("Duration:")
local var = tonumber(read())
local senderId, message, distance = rednet.receive(var) -- Am I using var correctly?
write("From: ") -- I think these last three lines are the problem
print(senderId)
print(message)

I've been messing around with this code for a while now and it never returns an error message when I run it. It seems to work fine and it always waits the time I specify but when I send a message to this computer it doesn't stop waiting and it doesn't print the senderId or message.

Var is used correctly there to timeout the receive. Are you opening rednet in the computer?

I did make sure that both the sending and recieving computers were open. I also made sure I was using the right computer ID when I sent the test message. The computer looks like this when I run it.

Duration:
20			 -- I enter the duration and it waits the correct time
				 --no matter how soon I send the message it still waits exactly the duration I entered and after the timeout is up it prints a blank line
>               -- after that it just goes back to the normal ">" and waits for me to do something

Are you sure you didn't make a typo within the opening of the modems, and you didn't close them before sending?

Post both codes here so we can see them

This is the program I used to open my connection. I assumed it was working because the modem lit up when I used it.

term.clear()
term.setCursorPos(1,1)
print("Do you want to open or close a connection?")
local var0 = read

if var0 == "open" then
  print("Which side would you like to connect?")
  local var1 = read()
  rednet.open(var1)
end

if var0 == "close" then
  print("Which side would you like to disconnect?")
  local var2 = read()
  rednet.close(var2)
end

Ahhhhhhh! Sorry guys. I made a stupid.
The program I was using to send test messages looked like this:

print("Target ID:")
local var1 = tonumber(read())
print("Message:")
local var2 = read()
rednet.send(13,"have a fish",true) -- I slapped myself when I read this line
