Free Trial

I cannot get Free Trial Membership to present properly to users. The registration form tells them their intial payment will be 12.99 and their monthly payment will be 12.99. How do I get zero to show for the initial payment.

I am trying to get a free trial of one month and monthly payments of 12.95 thereafter. Whether it interacts properly with Paypal or not I don’t know. At this point I am just trying to communicate properly on the Register form for the customer.

I have tried checking free trial and not checking it. I have tried putting 0 into the intial payment and nothing changes the message to the potential customer.
