How can I calculate the signups for more than one spot?

My students have the option of signing up for more than one spot. How can they do that and get the total calculated?

Can I use the multiple choice field and the form calculation widget?

Do you mean to limit the number of registrations on the form? As I check your JotForm, I notice that you are already using Gift Registry widget. The Gift registry widget can be configured to select multiple options and with a maximum number of selection.

Are you experiencing any issues with the widget? Please get back to us with more information or if you need any further assistance. We will be happy to help.
