bari, Some of the shortcodes you are trying to use are new shortcodes that where intrduced in a later version of the WP eStore plugin. I have emailed you an updated version of the eStore plugin. The <!--show-wp-shopping-cart--> shortcode is for the simple shopping card not the WP eStore shopping cart. The following URL has a list of the shortcodes for the WP eStore plugin.
