wa_auth_rule error

I am getting the following error, can someone help. I'll attach the page. Thanks

Fatal error: Call to undefined function: wa_auth_rulepasses() in /homepages/44/d232789399/htdocs/buyorsellvideos/buy/games/NintendoDS/buynintendodsgames.php on line 147

You page is missing the code to attach the security assist files.

Add the following at line 2:
<?php require_once( "../../../WA_SecurityAssist/Helper_PHP.php" ); ?>

I did what you said now I am getting a new error:

Parse error: syntax error, unexpected ')', expecting T_VARIABLE or '$' in /homepages/44/d232789399/htdocs/buyorsellvideos/buy/games/NintendoDS/buynintendodsgames.php on line 40

I attached the page again.

Line 40 is:
if (isset()) {

Line 39 - 47:
colname_welcome = "-1";
if (isset()) {
$colname_welcome = (get_magic_quotes_gpc()) ? : addslashes();
}
mysql_select_db($database_connDB, $connDB);
$query_welcome = sprintf("SELECT * FROM Users WHERE UserID = %s", GetSQLValueString($colname_welcome, "int"));
$welcome = mysql_query($query_welcome, $connDB) or die(mysql_error());
$row_welcome = mysql_fetch_assoc($welcome);
$totalRows_welcome = mysql_num_rows($welcome);

is the code for the welcome recordset. The problem is that there no run time bvalue given to the variable you have created in the recordset.

Double click the recordset to edit it and fix the variable

I changed this:
colname_welcome = "-1";
if (isset()) {
$colname_welcome = (get_magic_quotes_gpc()) ? : addslashes();
}

To this:
$colname_welcome = "-1";
if (isset($_SESSION['UID']) || $_SESSION['UID'] != '') {
$colname_welcome = (get_magic_quotes_gpc()) ? $_SESSION['UID'] : addslashes($_SESSION['UID']);

I had this working on a another page and just copied it and pasted it. It is working now. Is this ok?

Sure, looks like it should work.
