Hi Carla, if you have created your form in Google Forms, then you can customize it using the Neartail addon to add amount calculations and enable payments. Once you customize your google forms, the form will be added to the Neartail dashboard. You can login to Neartail, click on the form to open it and then make edits directly using the Neartail Editor. When you use the Neartail share link to collect responses, it will recorded in Neartail and Google Forms. You can also sync the responses to Google Sheets. If you haven't created your form yet, you can use the Neartail templates to create your apparel order form and the registration form.
