//PROBABLY DON'T NEED THIS ANY MORE BUT CHECK BEFORE IT'S REMOVED

//Structure: pageList[i][0] - display name of the page
//           pageList[i][1] - name of the page, including path
//           pageList[i][2] - original row number (This is used when the array has been sorted to check against the value stored in the preferences cookie. It was necessary to do it this way to ensure that anyone who had saved preferences before the array was sorted would not have his/her prefences suddenly changing on them after the sorting code had been added, e.g. if a user had saved row 4 as an "à la carte" item before we added the code to sort the comboboxes in preference_links.php, row 4 in the pageList array could well have become row 21 after the sorting code was added, so instead of checking the cookie-stored preference against the row number, we check it against the "original" row number stored in the third column of the array. So there.)
