Auto populating the payment form section...

I want the payment section to be autopopulated from the ordering sheet when the items are checked.  So far this isn't and is just a blank with USD associated and the customer has to type in themselves.  

It's a service and there is not selection for that so it's the self selected one.

Also, how do i show the form fully vertical as opposed to it sliding horizontally?

You can set an amount to your Payment field by using a Form Calculation widget. Here are the steps to achieve your requirement.

1. Enable Calculation values to your product field. You can check this guide for instructions: How to Assign Calculation Value.

2. Add a Form Calculation widget to your form. Set the field to hidden so your form users will not be able to see the field.

3. Add the Product field to your Form Calculation field. For more information about Form Calculation field: How to Perform Form Calculation Using a Widget.

4. Set up Get Total From on your Payment field.

Thanks!  However, the form calculations ‘Total’ field didn’t have an option to make it not visible. That’s what I’d really like it to be.  Any suggestions?

You can right click on the Form Calculation Widget (or any field) on your form and select HIDE / SHOW to toggle its visibility:

Alternatively, you can also click the GEAR icon of any field > go to the ADVANCED tab > then toggle the HIDE FIELD option.
