Turtle Farm

I am new to Lua and I'm trying to explore different options in what I can do with computercraft. Right now I am trying to make a small wheat farm.

num = turtle.getItemCount(3)
while num ~= 32 do
  turtle.place()
  turtle.select(2)
  turtle.place()
  turtle.select(1)
  turtle.dig()
end

What I thought this would do was place the seeds in slot 1, select slot 2 with the bonemeal, use the bonemeal, select the seeds again and break it. This part works but the while loop goes on until the bonemeal runs out when I thought it would only go until the item count in slot 3 (where the wheat goes) was 32.
Again, I am new to Lua and this may be completely wrong. Help is appreciated!
Thanks! :D/>

Crap! Just realized I put this in the wrong place! How do I move it?

I'm also new to LUA, but this might work.Let me know. :)/>

num = turtle.getItemCount(3)
while num ~= 32 do
  turtle.place()
  turtle.select(2)
  turtle.place()
  turtle.select(1)
  turtle.dig()
else
print("Wheat has been collected!") -- or whatever you want it to say when its full.
end

or…

num = turtle.getItemCount(3)
while num ~= 32 do
  turtle.place()
  turtle.select(2)
  turtle.place()
  turtle.select(1)
  turtle.dig()
else
if num ~= 32 then
print("Wheat has been collected!") -- or whatever you want it to say when its full.
end
end

Maybe someone could vouch this…?

Click the Report button under the opening post and put your request to move it to Ask A Pro in the message.

The problem is that 'num' (the itemcount in slot 3) is never updated since it isn't part of the loop.
The correct code would be:

num = turtle.getItemCount(3)
while num ~= 32 do
  turtle.place()
  turtle.select(2)
  turtle.place()
  turtle.select(1)
  turtle.dig()
  num = turtle.getItemCount(3)
end

Or, to make people comfortable with other kinds of loops:

repeat
  turtle.place()
  turtle.select(2)
  turtle.place()
  turtle.select(1)
  turtle.dig()
  num = turtle.getItemCount(3)
until num == 32

Depends on how strict he is about the condition. (in your case it will get executed at least once)
Anyway: for both our solutions the condition should be changed to:

while num < 32 do
...
end

Or:

repeat
...
until num >= 32
