"no buses" means the program ran but couldnt find a good result. Check out the data file to see the timings of the buses. If you're running the app at a time BEFORE the time of the bus/ferry, it will show the next bus. ie, If there are the following in the data file, New York Chicago 1000 New York Chicago 1500 and you run the script at 1600, the result will be no buses But if u run itat 1100, the result should be shown correctly. GUI work was stopped temporarily. I am still figuring out how to make the GUI elements do something, instead of sitting there all pretty.
