[Turtle]Whats wrong with my code?

Hi,
this is my first try to program a turtle. The turtle should built a house without roof. x,y,z are width, length and height.
When i try to run this i get this error: bios:206: [String "house"]:36: "=" expected

x=5
y=4
z=3
turtle.select(1)
turtle.turnLeft()
turtle.forward()
turtle.turnRight()
turtle.forward()
turtle.turnRight()

for var1=1,z,1 do
for var2=1,x,1 do
  if turtle.compare()== false then
   turtle.dig()
   turtle.place()
  end

  turtle.turnLeft()
  turtle.forward()
  turtle.turnRight()
  end

turtle.forward()
turtle.turnRight()

for var3=1,y,1 do
  if turtle.compare()== false then
   turtle.dig()
   turtle.place()
  end

  turtle.turnLeft()
  turtle.forward()
  turtle.turnRight()
  end

turtle.forward()
turtle.turnRight()

end

I really dont know whats wrong. Plz tell me if you find a mistake.
Thank you.

Your missing an end, from the looks of it for the first for loop. Probably needs to go in at line 25

Nevermind that looks good, I'm looking.

Your missing ()'s after a couple turtle.turnRight()'s

thank you now it works. I have another question. Is it possible to check the number of items in a slot every time? So that when he runs out of items he switchs to the next slot?

You could use

turtle.getItemCount(slot)

for example:

slot = 1
if turtle.getItemCount(slot) == 0 then
slot = slot+1
turtle.select(slot)
end

thank you. I solved the problem with a function.
