RE: Next and Previous LInks
You need to use a LIMIT statement in your SQL. There is a function in PHP that is supposed to let you get the number of rows that would have been returned without the LIMIT but it frequently returns an error.

do this:
php Code:
Original - php Code 
  1.  
  2. $sql = "SELECT * FROM guests";
  3. $sql_result = mysql_query($sql,$connection) or die("Couldn't execute query.");  
  4. $entries = mysql_num_row($sql_result);
  5. mysql_free_result($sql_result); 

this gives you the total number of records.
Then do this:
php Code:
Original - php Code 
  1.  
  2. "SELECT * FROM guests LIMIT $start, 10"

note: $start must have a value of zero on the first page and after that you add x per page (in this case 10).
