I was unable to get any of the suggestions to work, except in_array().
However, the selected item refuses to become highlighted.
code:
<select name="categoriesIN[]" multiple size="8">
<?php
$sql = "SELECT * FROM categories";
        //$selected = ($id == $row)?'selected="selected"':'';
  if ( ( $results = mysql_query($sql, $db) ) !== false ) {
        while ( $row = mysql_fetch_assoc($results) ) {
            if (in_array($row['id'], $ccc)) {
              echo "<option value=", $row['id'], " selected >",
$row['category'], "</option><br />";
                  }
              else echo "<option value=", $row['id'], ">",
$row['category'], "</option><br />";
            }
        }
?>
    </select>
I can't find anything that explains why the selected item is not
highlighted.
