Increment Submission Counter widget based on user input

I am trying to use the submission form widget for a Sunday Service reservation form for our in-person service.

Is there a way to have the Submission Form Widget reflect the number in the party? Another word, if a person filling out the form has a party of four can the submission reflect 4 less verses just one for the submission of the form?

Is there a way I can talk to a person?

This is my form. I did a test submission for 4 people to attend the service. the submission number at the top only went down 1 instead of 4. We need to limit the number of available seats.

Unfortunately, we do not have phone support. Meanwhile, I assume you were instead referring to the Submission Counter widget.

Unfortunately, no, that is not possible since the widget simply counts the number of submissions regardless of any contents within it.

May I suggest instead that you add a summary that calculates the sum for your Number field within the Tables page, like below:
