**Chriistian**Hi,

Here are the steps to integrate your form to paypal:

1. Add Calculation Widget that will compute the Total amount ordered by your client.

2. Setup your Calculation widget formula: (Birthday Cake * 45) + (Pie * 20).

2. Hide the Calculation Widget so user cannot see this field.

3. Add Paypal Payment field.

4. Setup Paypal Payment to Collect Donations/Custom Amount Payments, uncheck This is a donation. We are a non-profit organization. option and set Get Amount From to the Calculation Widget field.

Do let us know if you need further assistance.

Regards.
