Issues with turtle.getItemCount/Space

So I've been getting into computercraft again, and while making an automatic obsidian generator program I ran into some issues.
This is my code:

if turtle.getItemSpace(2) >= input then
for i=1,amount do
  place()
  button()
  mine()
end
else
 print("Not enough redstone!")
end 

I'm always getting one of two errors: "Attempt to call table" or "Attempt to compare __le on table and string." For reference, I'm keeping redstone in slot 2 and trying to make sure there is enough of it for the obsidian request.

Post the functions and the error line numbers as well.

Entire code here and both errors occur on line 42

My bet would be that you've set one of these:

  place()
  button()
  mine()

To something like '{}' somewhere else in your code.
But please post your entire code.

Edit: Sorry, the above post didn't show up when I was writing. CometWolf's post looks correct though.

it's weird, there's nothing related to tables here

input = read()
amount = input/3
if turtle.getItemCount(2) <= input then

However, read() always returns a string, so using tonumber to convert it to a number is probably a good idea.

input = tonumber(read())

I suppose I should also note I'm using CC 1.56 EDIT: I have tried that fix, but I'm still getting an "Attempt to call table" error on line 42

And your not running any other programs prior to this? Try rebooting the turtle and running your program directly if so.

Right before line 42 do:

print(turtle.getItemCount)

If what it writes contains 'table' then I'm really don't know. If it says 'function' it shouldn't be giving that error.

Rebooting it worked, thanks! :D/>

You probably modified the function, make sure you avoid doing touching default APIs.
