Jerim,

Why don't you want the redirect before the HTML? If you redirect the
user, you don't want the HTML to show, do you?

It can still be conditional. Put it at the top, and if everything is
OK, just have it fall through to the HTML.

BTW - this is a very user-unfriendly way of doing it. You should rather
check all the options, then if any are incorrect, redirect with all of
the invalid information. This way if there are three things wrong, the
user must gets an error message for the first one and corrects it. Then
he gets an error message for the second one, and so on.

If you check them all, you can display all three error messages at the
same time. Much more user friendly.
