Creating a User Input Scoreboard on Wix

Hi all!
So I know this may sound a little strange but here is what I am trying to do. My job is holding a scavenger hunt for our workers. And I am tasked with creating a scoreboard that the team leaders will be able to update regularly. I’ve managed to create a good portion of it however I am stuck on something that I’m sure there is a work around for but I’m a little bit unsure of how to go about it.

So I have created the table I have attached it to a dataset and I have created the user input fields that all work. However what I am wanting is when I add points, that it will add to the previous score I submitted for the same previous team.

Is this a thing that is possible or a pipe dream? Here is the test site for an idea of what I have done so far:

(Scroll to where you see the table, or “Scoreboard” and the “submission” button is underneath that will go to a form where players can add scores.)
