Hello! I am having a huge form that is supposed to be filled by the app user. All of the fields will be on one screen. However, I decided to split the form into 4 forms, so I can better place them on the screen and thereby optimize the layout. For the user, the 4 forms should however appear as one. This is why I want to implement a single Submit button for all of the forms.

Set the OnSelectproperty of the "New" button to following:
