I get an error message saying that Traceback (most recent call last): File "C:/Python24/Example/area_cir_squ_regt.py", line 39, in -toplevel- print_options() File "C:/Python24/Example/area_cir_squ_regt.py", line 27, in print_options choice = input("Choose an option: ") File "<string>", line 0, in -toplevel- NameError: name 'c' is not defined What am I missing?
