How can you make a shopping cart with this? Each date is $5. I am having a
hard time adding it up for a total. Thank you so much.

I did check your form, and it seems you are trying to manually calculate the amount based on date field selection. Here are the steps you need to follow to achieve your requirement:

#1. Use regular form fields to list your products. It seems you have already added a multiple choice field, and you can continue to use that.

#2. Set "Calculation Values" for options you have added in multiple choice question. The following guide should help you how to set calculation values: https://www.jotform.com/help/301-how-to-assign-calculation-value

#3. Add "Form calculation" widget and set the formula to calculate the amount. The following guide should help you how to perform calculation: https://www.jotform.com/help/259-how-to-perform-form-calculation-using-a-widget

#4. Pass the final calculation value to the payment tool of the form to process payment. The following guide should help you: https://www.jotform.com/help/275-how-to-pass-a-calculation-to-a-payment-field
