Why when i trying to send a custom action in a form screen, glide create two row with correct data and that data below without setup from another one?
Hi 
Think you maybe adding an ‘add row’ action to a form this will create a duplicate entry.
You don’t need the action on a form to create a row.
See this discussion here 
Yes! It’s correct solution thank you🤝🏻
No problem glad it worked for you
