Scroll Button Skips a Page of Six Rows Pulled from Database

[vcprovenza]

I am a web design teacher a high school and need help with PHP. Our Staff Pages are on a carousel button. When pressed, it skips a page.

If you go to the Staff Page at http://www.cebyrd.com/staff.php and scroll, the scroll function reads 12 lines from the database instead of 6. So 6 teachers get skipped with every click of the car button. I don’t know why it’s skipping a page. Here’s my code:

<?php
                $row_ctr = 0;
                $open_LI = false;
 
                while($row = $res->fetch_assoc()) {
                  $row_ctr++;
 
          if($row_ctr % 3 == 1) {
                    $open_LI = true;
?>
                  <li>
<?php     } ?>
                    <div class="img_box">
                      <figure><a href="<?=$row['URI'];?>"><img src="http://bytes.com/images/staff/<?=$row['imageURI'];?>" width="182" height="186" alt=""></a></figure>
                      <div>
                        <p><a href="<?=$row['URI'];?>"><span class="red_font"><?php printf("%s %s",$row['firstname'],$row['lastname']);?></span><br>
                          <?=$row['title']?> - <?=$row['dept']?></a></p>
                        <a href="mailto:<?=$row['email']?>"><?=$row['email']?></a><br>
                                                <?=$row['phone']?>
                                      </div>
                    </div>
<?php
                  if($row_ctr % 3 == 0) {
                    $open_LI = false;
?>
                  </li>
<?php     } 
                }
 
                if($open_LI) {
                  $open_LI = false;
?>
                  </li>
<?php
                }
?>

The cause of this problem is the javascript used....

Also there's an error on your page:
Error Line 1428, Column 5: No p element in scope but a p end tag seen. </p>

But this is html, and not PHP ;)

Thank you so very much Luuk. I'm so lost and appreciate your help. I played around with the javascript and changed the "pageStep" from 3 to 2 and it's working perfectly. Thank you so very much for your help!

In gratitude,
