Paypal: Create a Recurring Payment button for Paypal

Hi I use Paypal and need a recurring payment setup. This USED TO BE really easy to do, but now suddenly the only way to do it is through EXPRESS CHECKOUT. I need a recurring payment for 5 x $50USD payments spaced out fortnightly. First payment happens immediately then one $50 every two weeks until expired. The final delivery of the payment button must be in the form of a URL like this: [login to view URL] This is one I have created already - it needs to be exactly like this but for 5 payments. So it will be: $50.00 USD for each 2 weeks, for 5 instalments Delivery must be a URL, as the URL needs to go on a sales template page that has already got the button created - so I just add the URL. I can only add a URL I cannot add HTML or add a button. URL ONLY. Pls start your reply with URL ONLY so I know you've read this far.
