Welcome to the forums @mikemoli!
Looking at the code, the issue is probably that the move_to function does not return new all the time, instead only returning new when the condition if new < to: is true. This leads the move_to function to return null when the condition is not met, which causes the issue you are seeing later in the code because position.x is set to null.
You probably want to move the return new code down a single indentation, so it is not linked to the condition. Lines 34 to 37 would then look like this:
if new < to:
new = to
return new
Then I think it will work as expected.
