I'm using this plugin called WP Auctions with the List plugin, and as you may have guessed, it is to display a list of auctions on a page much like eBay where users can bid on items. It is simple to set up. I just need to activate it and plug in the shortcode.
The reason why I am having trouble is because I want users to be able to sort the list of auctions by price and date. This is not built into the plugin unfortunately.
