Hi, I am using your plugin and its superb but I am stuck on using it. I have created a pricing table using a plugin and I want to place the link to my paypal page using your plugin [shortcode] but it ask for link means I have to put http://xyz.com but I want to enter your plugin shortcode so that when clicked on it, it will redirect to paypal page.
