When going to the products and selecting a product, easycart will take you to the page and all that products options are available. You can select the product and the desired option shows selected. However, it remains as the default option regardless of which option is chosen. When choosing checkout, the default options are still the only items added to the cart. We are not sure if this is an option we've setup or if this is a little error in the code.
Easy cart has improved a lot. Just a few more little things to work on. Overall, we've been very happy with Easycart.
