CSS Profile- how do you look up Help Codes

<p>When filling it out the CSS Profile, each question has a Help Code next to it. You can click on some of them and it takes you directly to the explanation. For the ones that you can't click on, how do you look up the Help Code? If I type the exact code in the Search Help box as it instructs (no spaces), it just says nothing found for search criteria. How then do you look up the Help Codes?</p>
