Payable form: add Paypal to your Google Form

Description

** Now with Google Analytics integration to track the performance of your form.
** Now support embedding your form in iframe.

Angus Kidman, Australia's most experienced and dynamic writers on technology describes this app on Lifehacker:

"
Using Google Forms to collect information and want to integrate a secure PayPal connection? This simple app generates the link you need.

Specify the key details: the email address the payment will be sent to, your product name, price, currency (USD, AUD, CAD, GBP, EURO and major currencies are supported), and whether you want a one-time or recurring payment, then add the relevant form address. You can optionally add a company logo and additional CSS. Once the form is completed, your user is automatically redirected to the PayPal payment screen. Handy.
