Unicef - donate help set up

Hi I need help with how I would set up a donation system for a charity website similar to the unicef page.

As you can see, payments can be made using the tabs or selecting a monthly payment.

I basically want to copy this and have it on the charity website I am designing. I could copy it in terms of design but getting it to work is a different matter.

Think this would be useful for any other designers who are building websites for charities in the future as it’s a great feature rather than a standard paypal donate link.

Many thanks
