I want to have a monthly sub option as well as a one-pay

I want to have a monthly sub option as well as a one-pay yearly option using PayPal express and PP single payment.
here are the pages
http://wheretofindcustomers.com.au/register/
which leads to http://wheretofindcustomers.com.au/register/?action=registeruser&subscription=1

It shows two buttons. It should only show the $19.95 button on that page and the $97 button on the other page

I can't find how in your documentation. Help please?
