When delete "thing" change other related "thing"

Dear friends,
I’m new here and I have a question.

I created an RG with game results and a list of players who scored goals.

When I add this new game and the players who scored, the player’s goal count increases.

Now, I have doubts about how to reduce the goal count when I delete this game from my list, the goal count does not subtract in the player table.

Can someone help me?

Well have you created a workflow to do just that? The ‘goal count’ won’t decrease unless you make changes to it.

I just did, but now I have a new problem…
I was adding the players to a list, but I didn’t know I couldn’t duplicate the player… I’m looking on the forum for how people resolve this type of situation and I haven’t found it yet.
Would you have any suggestions?
