Button to checkout via PayPal in Appointments+ Appears outside of form

http://www.nonage.org/client/tgf/test/

After clicking on "Please click here to confirm this appointment," the PayPal button ("Please confirm AMOUNT USD payment for SERVICE") appears but it is outside of the app_confirmation form.

Is there a way to make the "Please click here to confirm this appointment" button take the customer to PayPal - rather than showing another button they have to click?

If not, is there a way to make the "Please confirm AMOUNT USD payment for SERVICE" button appear closer to the "Please click here to confirm this appointment" button. In this case, can it also by styled differently than the "Please click here to confirm this appointment" button - for example, make the background green so it really stands out.
