HW3 Done

This is the homework where I de-bugged the adder.php page.  I found about 10 errors. I didn't track how long it took, so I suppose I missed that lesson. Perhaps the most helpful thing to come out of this homework is that I now understand how an If/Else statement with the closing php tag right after the else's opening works to either print the 'IF' statements (which are inside the php tags) or the 'ELSE' statements/html (which is outside the php tags). So I think I did well enough to declare this assignment done.
