How to check compulsary fields and save the form?

[toiop33129996]

I would like to make possible to the user to save the form only if all the compulsary fields are complete, because it only works with the submit button.

You can't really do that. However, you can force the saved file to be blank if not all the required fields are filled in, or you can display some kind of error message. See this tool I've developed to do just that: Custom-made Adobe Scripts: Acrobat -- Validate Required Fields Before Printing or Saving
