My bad, I just copied the code wrong .... assuming I have all that fixed

I've stumbled on this:

The move_loans method works if I use this code below as I get the
output:

def move_loans
     puts(amount_of_loans - amount)
end

But if I replace the body with what I really want, it throws the error:

def moves_loans
     amount_of_loans = amount_of_loans - amount
end

It seems to be THAT body right there that's throwing the error...what's
going on??!!
