Updating Discount Code Table Error

I have the attached confirm.php page. See the PM for the error I am getting. I added two server behaviors to this page that is likely causing the error. First, I want to locate the recordset "discounts" based on the session variable "PromoCode". Next, I want to update that recordset field "discountStatus" with the number 1 if the order submission is successful. The errors I am getting are:

Warning: mysql_select_db() expects parameter 2 to be resource, null given in /home/content/05/11651305/html/(my domain folder)/confirm.php on line 44

Some code, including your database connection, got placed too low on the page. It also looks like there is some garbage on line 1. Try moving lines 58-60 to the top and remove line 1.

Thank you Ray. I was able to submit an order now. However, the update I was intending to do did not work. I added the following code to accomplish adding "1" to discountStatus with the rule "Successful update". Do you know why this might not be working also?

<?php
// WA DataAssist Update
if (WA_Auth_RulePasses("Successful update")) // Trigger
{
$WA_connection = $PowerStoreConnection;
$WA_table = "discounts";
$WA_redirectURL = "";
if (function_exists("rel2abs")) $WA_redirectURL = $WA_redirectURL?rel2abs($WA_redirectURL,dirname(__FILE__)):"";
$WA_keepQueryString = false;
$WA_indexField = "discountCode";
$WA_fieldNamesStr = "discountStatus";
$WA_fieldValuesStr = "1";
$WA_columnTypesStr = "none,none,NULL";
$WA_comparisonStr = "=";
$WA_fieldNames = explode("|", $WA_fieldNamesStr);
$WA_fieldValues = explode($WA_AB_Split, $WA_fieldValuesStr);
$WA_columns = explode("|", $WA_columnTypesStr);

$WA_where_fieldValuesStr = "".$_SESSION['PromoCode'] ."";
$WA_where_columnTypesStr = "',none,''";
$WA_where_comparisonStr = "=";
$WA_where_fieldNames = explode("|", $WA_indexField);
$WA_where_fieldValues = explode($WA_AB_Split, $WA_where_fieldValuesStr);
$WA_where_columns = explode("|", $WA_where_columnTypesStr);
$WA_where_comparisons = explode("|", $WA_where_comparisonStr);

$WA_connectionDB = $database_PowerStoreConnection;
mysql_select_db($WA_connectionDB, $WA_connection);
@session_start();
$updateParamsObj = WA_AB_generateInsertParams($WA_fieldNames, $WA_columns, $WA_fieldValues, -1);
$WhereObj = WA_AB_generateWhereClause($WA_where_fieldNames, $WA_where_columns, $WA_where_fieldValues, $WA_where_comparisons );
$WA_Sql = "UPDATE `" . $WA_table . "` SET " . $updateParamsObj->WA_setValues . " WHERE " . $WhereObj->sqlWhereClause . "";
$MM_editCmd = mysql_query($WA_Sql, $WA_connection) or die(mysql_error());
if ($WA_redirectURL != "") {
if ($WA_keepQueryString && $WA_redirectURL != "" && isset($_SERVER["QUERY_STRING"]) && $_SERVER["QUERY_STRING"] !== "" && sizeof($_POST) > 0) {
$WA_redirectURL .= ((strpos($WA_redirectURL, '?') === false)?"?":"&").$_SERVER["QUERY_STRING"];
}
header("Location: ".$WA_redirectURL);
}
}
?>

I'm not sure what you are going for here. What is the rule "Successful update". Why not use the same button press rule as the Store cart Summary below?
