[LUA] Whats wrong with this code?

Im pretty new to ComputerCraft and Lua, although I do have some experience using other languages, so I'm hoping someone could help me figure out why this program isn't working the way it should. I made a simple program for my turtle, where it listens for a rednet message, and preforms a certain action, depending on what it receives. If it receives a message that isn't one of the things it reacts to, it broadcasts "error", and the program ends. When I run the program, it broadcasts "error", no matter what message it receives.

print("Minion Mode Engaged")
rednet.open("right")
while true do
id, message = rednet.receive()
print("Message receive")
if message == "go" then
	turtle.forward()
elseif message == "up" then
	turtle.up()
elseif message == "down" then
	turtle.down()
elseif message == "left" then
turtle.turnleft()
elseif message == "right" then
turtle.turnright()
elseif message == "detect" then
rednet.broadcast(turtle.compare)
elseif message == "done" then
break
else rednet.broadcast("Error "..message )
break
end
end

I'm sure I'm just making some simple mistake, but I don't know what it is.

That code is fine, the problem must be in the sender, or maybe there's other computer broadcasting, so it gets the wrong message.

Also, you should change this line:

rednet.broadcast(turtle.compare)

to this:

rednet.broadcast(tostring(turtle.compare())) -- added () and tostring()

You're right. The code was fine. I had a temporary moment of stupidity. The 2 commands I tried sending it were "forward" and "back", which, if you examine the code, you'll see are not in it. Although I did use turtle.turnleft and .turnright instead of turnLeft, and turnRight. You were also right about adding tostring. Without it it gives an error message saying "String expected". I never would have been able to figure out to fix that. Thanks :(/>/>
