If you have only a *FEW* (like, under a hundred) "shot_num" in a single movie, just do this: <?php $query = "select shot_num, start_time from whatever order by shot_num"; $shots = mysql_query($query) or error_log(mysql_error()); echo "<SCRIPT LANGUAGE=JavaScript>\n"; while (list($shot_num, $start_time) = mysql_fetch_row($shots)){ echo " shot_num[$shot_num] = $start_time;\n"; } echo "</SCRIPT>\n"; ?> Now you can just look up the shot_num in JavaScript. You may want to switch the array around or whatever it takes to make JavaScript capable of finding/searching the shot_num/start_time lookup. -- Like Music? http://l-i-e.com/artists.htm I'm looking for a PRO QUALITY two-input sound card supported by Linux (any major distro).
