proof check and two errors - unassigned variables from one method to another
<p>I'm a big fan of having people that can check work no matter what it is.  Whether it is essays, projects, or just habits (drawings), I like feedback to help me get better.  Below is my code to a project I was working on for school.  I got it pretty much finished and there is two errors inside of it.  The errors are inside of Main() - GetInput() -----it is throwing two errors for the reference variables nameList and playerScore and saying that they are unassigned.  Not sure why, because I have them assigned as far as I know of.  however, any help with that would be great but I'm also looking more for feedback on if I could of done anything better or easier, while following the directions in the comments. I have to use arrays and I have to pass them by reference between the methods while passing the avg variable by value.</p>
