Hi all i created a dynamic check box form. I let the user to select a few songs and once they click on submit all those values get passed to a second checkbox form. My first checkbox form data ouf of this query:

$query = "SELECT id,artist,track,album,title FROM files where album='$albumname' order by track";

The code beleow is part of my checkbox form.The values on bold are those that i need to display them in second page check box form. My problem is that i do not know how to pass those select checked box values to next page by using post method. I be happy if an expert show me how i can do it.Thanks
Note : the second form needs to be dynamic too since number of passed values are not the same each time!

Code:
<form method="POST" action="./Members/AddToPlayList.php"  name="mp3Play"> 						 <tr>

?>
   while($row = mysql_fetch_assoc($result))
{
    						
 <td bgcolor="#C0C0C0"><p align="center"><b><?=intval( $row['track'] );?></b></p>
                        </td>
                        <td bgcolor="#C0C0C0"><input
                        type="checkbox" name="Id" value='<?=intval( $row['id'] );?>' /></td>

                        <td bgcolor="#C0C0C0"><a
                        href="javascript:newWindow('./mp3s/myWimpy.php?queryWhere=Id&queryValue=<?=strval( $row['id'] );?>')"><img
                        src="images/Speaker.gif"
                        alt="Listen to this Song" border="0"
                        width="16" height="16"
                        longdesc="Listen to this Song"></a>&nbsp;<?=strval( $row['title'] );?>
                        </td>
                        <td bgcolor="#C0C0C0"> <?=strval( $row['album'] );?>  </td>
                        <td bgcolor="#C0C0C0"><a
                        href="javascript:newWindow('RateSong.asp?SongID=1')"><img
                        src="images/RatIt.gif"
                        alt="Rate This Song" border="0"
