Update multiple rows in a single query?

I need to update multiple rows with a single query and having some problems - see code below:


<?php //location header - update 'claims_submission' page = auto_assign.php

if (@$_REQUEST['save']) {
 for($i=0;$i<$count;$i++){
 $sql1="UPDATE 'claims_submission' SET independent_dispatcher='$independent_dispatcher[$i]', independent_adjuster='$independent_adjuster[$i]' WHERE idd='$id[$i]'";
 $result1=mysql_query($sql1);
 }
 }
?>

<!-- PHP Form -->
<form action="auto_assign.php?" method="post">
<?php $id = ""; ?>
    <?php foreach ($claims_submissionRecords as $record): ?>             
    <?php $id[]=$record['num']; ?>

    
    
<td align="center" height="35" bgcolor="<?php echo $bgColor ?>"><font face="Verdana" size="3">
<!-- Select A Independent Dispatcher -->
  <select id="inddispatcher_drop" idd="independent_dispatcher "name="independent_dispatcher[]"> 
        <?php foreach ($independentAdjusterDispatcherDistanceToRecords as $distance => $users): ?>
          <?php foreach ($users as $user): ?>
            <?php if ($user['user_type'] == "Dispatcher" AND !$user['disabled']): ?>
              <option value = "<?php echo $user['num'];?>"><?php echo $user['fullname'];?> - <?php echo $distance != "Distance NA" ? $distance." mi" : 'Distance NA'; ?></option>
            <?php endif; ?>
          <?php endforeach ?>
        <?php endforeach ?>
        <?php foreach ($independentAdjusterDispatcherDistanceToRecords as $distance => $users): ?>
          <?php foreach ($users as $user): ?>
            <?php if (($user['user_type'] == "Dispatcher/Adjuster" OR $user['user_type'] == "Dispatcher/Processor" OR $user['user_type'] == "Dispatcher/Processor/Adjuster") AND !$user['disabled']): ?>
              <option value = "<?php echo $user['num'];?>"><?php echo $user['fullname'];?> - <?php echo $distance != "Distance NA" ? $distance." mi" : 'Distance NA'; ?></option>
            <?php endif; ?>
          <?php endforeach ?>
        <?php endforeach ?>
     </select>
<!-- //Select A Independent Dispatcher -->

<?php endforeach ?>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
  </table>
  <p>&nbsp;</p>
  <p>
      <br/>
  <input class="auto-style3" type="submit" name="submit" value="Assign Dispatchers, Adjusters & Processors &gt;&gt;" /><span class="auto-style3">
  </span>
    </td>
   </tr>
  </table>






I have only listed the primary code above that I feel I'm having problems with as the entire coded page would be to lengthy for viewers to search through. I feel it is within the '$i", '$id" or 'idd' sets and I can't seem to get a handle on it

Even though rows are present and changes have been made, nothing is updated upon submit and I receive no errors - any ideas on what I'm doing wrong?

Thanks - nmsinc
