We managed to define a method called total_trip and passed variables ie starting_line, starting_point for the method to operate on. Then we created a code block to handle the equations using if and else. so far we've only been able to return a result using hard coded strings i.e. the various lines and station names. The result is correct but this evening we could not create an input to return those results. I have commented out my first attempt I also tried using some of the code from yesterday's calculator ie creating a menu with (n)line (s)ix line (l)line but so far I cannot resolve it.
