Hello
i have a problam i dont let the data insert in the database when i
refresh on a page .
How can i prevent ???
------------------------------
The best way to do this is to search the dayabase first for a unique value 
that has already been added and don't add if it already exists.

A cheep and nasty way is -
<?php
session_start();
if(isset($_POST["submit"]) && !($_SESSION["posted"]))
  {
  $_SESSION["posted"] = TRUE;
  // do mysql stuff
  }
