Turtle won't move forward

Hey! RiokuTheSlayer here,and i have a bit of a problem…..

I'm making a program that can control a turtle from a computer.
But the turtle won't move forward or backwards.I can,however,make it rotate.
Here's the code.
Computer:

rednet.open("back")
sleep (1)
print "This is the programs to control the turtle"
sleep (1)
print "Controls: W=Forward S=Backward A=Rotate Left D=Rotate Right."
while true do
local event, param1 = os.pullEvent ("char")
if param1 == "w" then
   rednet.send(1,"W")
elseif param1 == "s" then
   rednet.send(1,"S")
elseif param1 == "a" then
   rednet.send(1,"A")
elseif param1 == "d" then
   rednet.send(1,"D")
end
end

(may have a few space errors from copy/paste)

Turtle:

rednet.open("right")
print("This is the turtle to be controlled.")
sleep(1)
while true do
  local senderId, message, distance = rednet.receive()
   if message == "W" then
	turtle.forward()
   elseif message == "S" then
	turtle.back()
   elseif message == "A" then
	turtle.turnLeft()
   elseif message == "D" then
	turtle.turnRight()
  end
end  

Any help would be greatly appreciated!

Thank you for your time,

Put any resource that you can burn in an furna e into the inventory of the turtle and type then 'refuel all'

Now your turtle has fuel to move forward, 1fuel per block

Well,i knew about that.But what if i don't want fuel? i couldn't find the option for it in the file. Could you give me the place it's found? Unless they made it always have to have fuel in the update…

Oh,i found it. thanks for the info!
