Warning: Wrong parameter count for mysql_result() in /home/httpd/vhosts/com/

[oskare100]

Hello,
When I rund this part of the script:
[code=php:0]$sql13 = "select account_username from paypal_sales where txn_id = '$txn_id'";
$result13 = mysql_query($sql13) or die( mysql_error() );
$del_account_username = mysql_result($result13);
echo "Username: $del_account_username";[/code]

I get the error:
Warning: Wrong parameter count for mysql_result() in /home/httpd/vhosts/com/

What does that mean? There is a value for account_username in the table paypal_sales where the txn_id in the database is the same as the $txn_id variable in the script.

Best Regards

mysql_result() takes a minimum of 2 parameters: the result ID and the row number. You also typically need to pass the column name of the value you're after, too:
[code]
<?php
$del_account_username = mysql_result($result13, 0, 'username');
?>
[/code]
