Conditional formatting for PHP repeat region

Hi

I have a repeat region displaying a recordset. I would like to apply some form of conditional formatting if a result meets a certiain condition. In my code below, I would like the 'onsched' field to display according to a specific class if the result is less than 0:

<?php do { ?>
        <td><?php echo $row_RSonsched['name']; ?></td>
        <td><?php echo $row_RSonsched['predcurrent']; ?></td>
        <td><?php echo $row_RSonsched['Emerging_Level']; ?></td>
        <td><?php echo $row_RSonsched['onsched']; ?></td>
        </tr>
        <?php } while ($row_Recordset2 = mysql_fetch_assoc($Recordset2)); ?>

Being new to PHP, is there any way I can have the class '.clsgood' apply if the value of ['onsched'] is less than 0?

Many thanks for your help in advance
