teginc on "[Plugin: WooCommerce - excelling eCommerce] Products dont ad in to cart?"

I've yet to get Woocommerce to add any product to my shopping cart. It redirects me to the page and displays "Your Shopping Cart is Empty".

I've tried everything and I can't figure out why it won't add products to my cart.
Thanks for help.
