If I'm following you right, you just need an SQL statement:
$sql = "SELECT tblGuestBook.Name, tblGuestBook.Email FROM tblGuestBook
ORDER BY tblGuestBook.Name";
$sqlresults=mysql_query($sql)
or die(mysql_error());
while($row=mysql_fetch_array($sqlresults))
{
$GuestName=$row["Name"];
$GuestEmail=$row["Email"];
echo "$GuestName<br>$GuestEmail<br>";
}
Instead of the echo, you would probably want to throw it into a table and jazz it up.
