Body ids, showing urls?
<p>I have a 4 pages with navigation.</p>

<p>Basically i have 4 pages.</p>

<p>P1 - shows all 4 pages but you can only click on the next page, page 2</p>

<p>P2 - shows all 4 pages also but you can go back to previously viewed pages ie page 1 and only go onto the next page page 3</p>

<p>P3 - shows all 4 pages also but you can go back to previously viewed pages ie page 2 &amp; 1 and only go next onto the next page page 4</p>

<p>P4 shows all 4 pages and will let you go back  to previously viewed pages ie page page 1,2,3 &amp; 4</p>

<p>My problem is - say you have gone through each page to the end page P4, and you click on page P1 to double check something, i want P1 to know you have completed all the steps and now now allow you to click page to page 3 or 4 etc. </p>

<p>can you do this using body id's?</p>
