With the categories_results.php page you helped me fix, I realized this morning that using the "and" separator returns all the products right now because they are listed as: test product 1, test product 2, etc.
Since the name field is probably not something that they will use to search (because these products are all used and refurbished, there isn't a standard inventory of 1 item), I thought the best thing would be to turn the search page into a drop down menu of categories and/or manufacturers.
I copied the original search page and renamed it: searchmenu.php I was able to change those fields to menu fields without any issues, but the results are still showing ALL products, regardless of manufacturer or category selected.
In the categories_results.php page, what would I change in the server behavior?
