Coupon Code for Subscription Membership Registration

Using this plugin for wordpress: [login to view URL] Have had some customized work done and the coupon feature is not working. I need this to work properly, specifically to take off $9.99 (1 month) from the new subscription. The process needs to display that the coupon took off the amount on the payment page. It should display "You will pay $0.00 upfront and $9.99 a month after." This also needs to be configured correctly with [login to view URL] so that the recurring billing doesn't start until the next month. If the subscription is annual, the coupon should just take off $9.99 the $99.99 annual subscription. **This needs to be completed in 5 hours or less** Do not bid if you cannot complete in that time.
