Since I am still learning, I just wanted state the logic of the code.
First we set $FName equal to nothing. Then we set $errorMsg1 equal to
nothing. Next we say "if the method is $_POST" then check to see if
$_POST['FName'] has been set. If it has, then set $FName equal to
$_POST['FName']
I still can't get it to display the error message.
