[Lua] Problem with repeat loops and timers

Hello. In a section of my quarry rednet receiver program, there is a part where it should wait for either a message or a five second timer, however it does not ever activate for the timer. I cannot figure out what I'm doing wrong. Can anyone help?

local message
local timeWaited = 0

term.clear()
while message ~= "stop" do
repeat
local id = os.startTimer(interval)
local event, idCheck, sendChannel, _, locMessage, distance = os.pullEvent()
message = locMessage
if (event == "timer" and idCheck == id) then timeWaited = timeWaited + interval else timeWaited = 0 end
until (event == "modem_message" and idCheck == modemSide and sendChannel == sender) or (event == "timer" and idCheck == id)
sendMsg(relayMessage)
--Text to screen stuff
end

That is because interval is never defined, you should have a number as integer. Eg. 1 and 4, every number that has no decimals. That is a double; 0.24

Oh I'm sorry, interval was assigned in the config. Currently interval is set to 5

So is this a bug or what?

Whats with having just

local message

and not define the message? Or is there more to your code?

If you define the variable without giving it a value, it will maintain the same scope throughout the entire program (or at least until you define another variable with the same name, in which case the new variable will take precedence until you have exited the function).

@OP: What do you mean it never activates the timer? Your code works fine for me.

Well. When I use the full program, it will receive messages and display them to the screen, but it will not update a section that says "Seconds since last message." One thing to note is that this function is part of a coroutine. The other coroutine function just waits for read() to relay commands to the turtle.

@Engineer, there are no integers in lua, nor are there doubles. There is only numbers.

It was for the sake of the example

You should provide the whole code because the problem may lie in that; I was able to get this to run just fine. My guess is that the function that is supposed to write the time to the screen is not actually updating anything.

Ok. Here is the code. Sorry it might be a bit messy, but it was in the middle of being updated.

The part where it outputs time is line 84

Here is the turtle program that (should) work with this version of the receiver. Use the argument "-rednet true" when you start
