Products button to show ALL Categories
I have the 'Products' dropdown menu and products_results and products_detail working fine - see http://outofchaos.net/gsc/www/index.html
However if you just click the 'Products' button itself and not one of the dropdown options, it yields a dead result, I'd like it to link to a page that showed all categories something like http://outofchaos.net/gsc/www/products_results.php?Category_ID=?ALL? but I'm not sure what the syntax is that would yield the ?ALL? Could you suggest what it should be? Thank you
