I'm trying to create a table in php that would show the data on the mysql database based on the check box that is checked by the user. As you can see in this screen shot, it will have problems when you did not check on a checkbox before the one that will be the last: http://www.mypicx.com/04282010/1/

Here is my code:

if($_POST['general'] == 'ADDRESS'){
$result2 = mysql_query("SELECT * FROM student WHERE ADDRESS='$saddress'");
 ?>



<table border='1'>
<tr>
<th>IDNO</th>
<th>YEAR</th>
<th>SECTION</th>

<?php if ( $ShowLastName )
echo "<th>LASTNAME</th>" ?>

<?php if ( $ShowFirstName  )
echo "<th>FIRSTNAME</th>" ?>


<?php if ( $ShowMidName  )
echo "<th>MIDNAME</th>" ?>


<?php if ( $ShowAddress  )
echo "<th>ADDRESS</th>" ?>


<?php if ( $ShowGender  )
echo "<th>GENDER</th>" ?>

<?php if ( $ShowReligion  )
echo "<th>RELIGION</th>" ?>

<?php if ( $ShowBday  )
echo "<th>BIRTHDAY</th>" ?>

<?php if ( $ShowContact  )
echo "<th>CONTACT</th>" ?>
</tr>


<?php
while($row = mysql_fetch_array($result2))
  {?>
    <tr> 
    <td><?php echo $row['IDNO']?> </td>
 <td><?php echo $row['YEAR'] ?> </td>
   <td><?php echo $row['SECTION'] ?></td>


  <td><?php
   if ( $ShowLastName  )
  echo $row['LASTNAME'] ?></td>

    <td><?php
   if ( $ShowFirstName  )
  echo $row['FIRSTNAME'] ?></td>

             <td><?php
   if ( $ShowMidName  )
  echo $row['MI'] ?></td>


   <td><?php
   if ( $ShowAddress  )
  echo $row['ADDRESS'] ?></td>

  <td><?php
   if ( $ShowGender  )
  echo $row['GENDER'] ?></td>



  <td><?php
   if ( $ShowReligion  )
  echo $row['RELIGION'] ?></td>

  <td><?php
   if ( $ShowBday  )
  echo $row['BIRTHDAY'] ?></td>

  <td><?php
   if ( $ShowContact  )
  echo $row['S_CONTACTNUM'] ?></td>



   </tr>

<?PHP   }  ?>
    </table>

<?PHP }






mysql_close($con);
?>

What can you recommend so that the output will not look like this when you one of the checkbox before a checkbox is not clicked: http://www.mypicx.com/04282010/2/
