A pretty common issue is submitting the choices but not going to the final page which deals with payment. Even if you are a Sportsman License holder and submitting no money, you have to complete that page. When you successfully complete everything, a screen with a transaction number will show up. Always print a copy, take a screen shot, or write down that transaction number. That way, if there any issues that show up, you have a starting point to see what they might have been.
If you don't get to the screen with the transaction number, most likely it did not go through for a variety of reasons.
