Unable to move forward on this.
The index.php page has one search field. Though the URL has the correct parameter, it returns the whole Db.
The Prod_results.php page has three search fields (ProdNum, ProdName, ProdType). Though the URL has the correct parameter, only ProdNum returns the correct results. The other three return the whole Db.
I've edited source code and WA server behaviors multiple times, and even tried creating new pages (multiple crashes led me back to troubleshooting the existing pages).
The pages aren't loaded on a server.
