Remove mysql_query from line 8. It is repeated on line 9.

its not repeated i've saved the query in $query and then saved it in $result would u please suggest me how should i do it correctly??
thanks for the rep :)

comment line 9 and replace $query with $result,becuase you can't execute query twice ,check this code:

$result=mysql_query("SELECT * FROM setup WHERE id=".$_SESSION['id']);
//$result = mysql_query($query);

excute this ,the error will be disapear.
