Sometimes you might want to give your customers different payment options on your form. You can do this using Submit Actions and Routing Logic. First, create a radio button/dropdown list field on your form that contains the payment options you would like to provide.
I used PayPal, Check, and Bring Cash to the Event. Make sure you make this question required, or the user might skip this question by accident.
In your form, go to Settings > Emails & Actions > Submission Message. In this example, I have created a Custom message for when the end user selects the check and the Default Message when using cash. Logic can be based on a Radio Button, Checkbox, Dropdown List, Event Fields, or Number fields.
To add Routing Logic to the PayPal integration, click on the plus sign next to Advanced Settings > select the integration > Logic.
