Form Calculation: Formula to Sum Quantity and Price Fields for Total T-shirts and Total Cost

I have 4 designs on my form. Each design has 4 subfields under the order details section (Name, Qty, Size, Price). At the bottom of the form there are 2 fields:

1. Total T-shirts: this field should add up the amounts entered into the "Qty" fields for all 4 designs. So if I have 2 shirts for design 1, 1 shirt for design 2, and 2 shirts for design 3, I have a total of 5 shirts. The total t-shirts field should say 5 to reflect the number of shirts I selected.
2. Total Cost: This field should add up the amounts in the "Price" field for all designs.

How can I word this so that AI understands?

Hi Tamara,

Thanks for reaching out to Jotform Support. I inspected your form and saw that you used the Form Calculation widget. It's not possible to perform calculations with this widget to sum quantity and price. If you want to sell T-shirts, you should use the payment field. You can add a payment field and integrate it with one of the 40+ Payment Gateways that Jotform provides. Here’s a step-by-step walkthrough:

1. On your Workspace page, click on Create on the top-left side of the page.

2. Then, select Form, and then click on Start From Scratch.

3. Next, choose between Classic Form and Card Form, and you will be automatically redirected to Form Builder.

4. Now, in Form Builder, click on the Add Element menu on the top-left side of the page.

5. Add the fields that you want to have on your form, and then click on the Payments tab.

6. Click on the Payment Gateway you want to use (for example, Stripe), and then click on the Plug icon in the menu on the right side of the page.

7. In the window that opens, click on Add New Connection, click on Stripe, and then click on Next.

8. Select Test Mode or Live Mode under the X button on the right.

9. Enter a Connection Name, and click on Connect with Stripe.

10. Log in to your Stripe account if you are using the Live Mode. Since I’m on Test Mode, I’m selecting Skip this Form.

11. Finally, click on Save, select the newly added connection, and click on Use.
