$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result)){

if ($queryString == $row[activationkey]){

   echo "Congratulations! You have succesfully activated you account. You may now login.";

   $sql=("UPDATE users SET activationkey='' AND status='activated' WHERE username=".$row['username']);
