How do I include a contract in my form?

Also how do i add my logo?

You can use the Short Scrollable Terms widget or the Terms & Conditions widget.

Here's a guide on How-to-Add-a-Widget-to-Your-Form.

Also, how do I add my logo?

In Card Form Builder, just click the "Edit welcome page" button and then click the pencil icon to open the "Welcome Image Properties". After that, click the "Remove Logo" button and upload your own logo.

Hope that helps. If you have any questions, let us know. Thank you.
