Reading a file into 5 arrays

[mossberg]

My LoadFile function will not work. Attempting to read schedules into 5 parallel sub arrays.
I have attempted a few different methods which are commented out. I have 2 text files saved in the folder. tim and wendy.
when I attempt to use LoadFile the window disappears for a moment then bring me back to GetUserChoice. however the array remains empty and i receive no compilation error??

Did you make a change to the code, or just scold me?
