Hi, welcome to the forum!

What error are you getting?

Sorry, your code does not pass. Keep trying.

You should move the code nested inside the first `if` statement (except the first `print()` call) to your new function.

that’s the error

# Step 31

It’s time to move some code from the `move()` function to the `make_allowed_move()` function. Move the code nested inside the first `if` statement (except the first `print()` call) to your new function. Pay close attention to the indentation. Don’t forget to remove the `pass` keyword.

Code that’s indented all falls under the `if`. It looks like you missed the last two lines

``````            # display our progress
print(rods)
``````

These lines disappeared

yeah i did miss the last two lines, thank you!

Hey, so I am indenting what you have in green and eliminating the pass in make_allowed_move, but it is still not passing. I am still getting an indentation error Any tips?
