How can i show the name of a user that clicked a button in a repeating group?
I can’t manage to add a name to a list when someone presses a button how do i do that with create a thing or make changes to list of things?

You just need to use a text element to display the name… and only display it when the User has clicked the button.

I know that’s a very vague answer… but it’s a very vague question.

Maybe if you give a specific example of what you’re trying to do it might help

Do you need the name to go on a list or just to be shown on screen there and then? If it’s just the latter hit display data: current user’s username.

For the former have a data field somewhere with the format “list of users” and then on the button have a workflow for “make changes to a list of things” and add the current user to that list
