What I am trying/attempting to do it break down a given data file containing
one line of data into seperate arrays (first and last names, gender, and 5
grades). I am successful on the first pass, but on the second i get errored
out. I am first copying the data from my data file (please don't edit or
change it to fix the problem) followed by my program code.
