Hi, I am attempting to create an advanced form with 9 different search fields. I am using the WHERE 1 AND sql function to add onto the generated end sql function so I don't have to created over 300,000 IF statements. The code below is showing up this error: [quote]Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /var/www/vhosts/numyspace.co.uk/web_users/home/~unn_w11014928/public_html/search.php on line 261[/quote] I cannot seem to hit the nail on the bud to why it shouldn't work.
