Question

The following code works when i run it in localhost, but when I host it online, it gives an error.

if(isset($_POST['congressman'])){
    $congressman = $_POST['congressman'];
    $no_of_votes = mysql_result(mysql_query("SELECT no_of_votes FROM `tbcandidates` WHERE `identification_no`=$congressman"),0) + 1;
    $query=mysql_query("UPDATE tbcandidates SET no_of_votes = '$no_of_votes' WHERE identification_no = $congressman");

This line:

no_of_votes = mysql_result(mysql_query("SELECT no_of_votes FROM `tbcandidates` WHERE `identification_no`=$congressman"),0) + 1;

It says mysql_result(): supplied argument is not a valid MySQL result resource in etc..
