I'm trying to make a turtle that will move around via rednet commands and plant tnt mines that can be triggered by a rednet message.

When I attempt to run the program that starts the turtle receiving rednet commands and acting on them I get this error message:

bios:206: [string "mine_turtle"]:33:
'=' expected

I'm assuming that for some reason it is expecting an = sign on line 33 somewhere but I dont see why when the normal syntax for that command doesn't require an = and it has been used almost exactly other times in the code with no problem.

Code:

while true do
function dig()
  turtle.digDown()
  turtle.suckDown()
  turtle.down()
  turtle.digDown()
  turtle.suckDown()
  turtle.down()
  turtle.select(2)
  turtle.placeUp()
  turtle.digDown()
  turtle.select(1)
  turtle.placeDown()
end
function fire()
  redstone.setOutput("bottom", true)
end
function forward()
  turtle.forward()
end
function backward()
  turtle.back()
end
function left()
  turtle.turnLeft()
end
function right()
  turtle.turnRight()
end
function up()
  turtle.up()
end
function down()
  turtle.down()
end
rednet.open("right")
local event, p1, p2, p3, p4, p5 = os.pullEvent()
if event == "rednet_message: then
  if p1 == 0 then
   if p2 == "dig" then
	dig()
   elseif p2 == "forward" then
	 forward()
   elseif p2 == "backward" then
	backward()
   elseif p2 == "left" then
	left()
   elseif p2 == "right" then
	right()
   elseif p2 == "up" then
	up()
   elseif p2 == "down" then
	down()
   elseif p2 == "fire" then
	fire()
   end
  else
  end
else
end
end

When doing comparisons is == to assign values its =

So on this line


if event = rednet_message then

--it should be
if event == "rednet_message" then --the event type is also a string so you need to wrap it in quotes

if event == "rednet_message" then

Rednetmessage is a string, and as you might guess, a = was expected, you missed one

~~ok fixed that but its still giving the same error~~ Figured out why the error was still going, I misspelled function.
Its working fine now

You have all of your functions inside of the while loop. Move the functions outside of the loop.

  else -- you also don't need this remove it
  end
else  -same here remove it
end
end
