Form submit

I have added a form submit button to the bottom of a form with the action add new row in the datasheet.

Nothing happens when button is clicked.

A new row is only added when submit on top right is clicked, this submit option disappears when a new button is addedd. I cannot get data to populate in sheet when clicked.

Want to move this action to the button for user functionality.

Please advise.

To do that, you would need to use a Custom Form.
