Drupal Coupon Bug

Anyone who is proficient with e-commerce using Drupal, would be aware and familiar with Commerce Coupon the following would take within an hour or less to complete the following task. I installed the commerce module, along with the Fixed amt add on module for commerce coupon, but it's not subtracting the price from the total after checkout. Additionally I installed a batch coupon module, and successful completion would be for the coupon "testingcode" to take $30 off the final price. To test and see a demonstration of the module that isn't working, visit: [login to view URL] and click "add to cart".. then click on "checkout" and add the coupon "testingcode"
