How to use a Zoho Subscriptions hosted web page in a Zoho Site

I want to use a Zoho Subscriptions hosted web page in a Zoho Site... because I want web site users to be able to sign up for a 'plan' as defined in Zoho Subscriptions and then make a payment - all of which is supported by Zoho Subscriptions hosted web pages (if I understand it correctly). Surely I can use those web pages in a Zoho site??

Thanks
