Deleting records from a blank subform

Deleting records from a blank subform

Welcome everybody,

I have a form with two subforms: a blank form and an existing form.

When you add a subform field to your form, you need to define if the subform is a:
  • Blank Form: This option enables you to create a form within the main form such that, the subform's existence is inside the main form
  • Existing Form: This option enables you to add an existing form (present in your app) as a subform
========================================================================

I am trying to delete records from the subforms. While it works fine for the records of the existing form following this :

 i cant find a solution to delete records form the blank (sub)form.

  1. delete from blank_subform[ID == deleteThisID];
When I try so save a script like the above, i get an error message:

Form 'blank_subform' does not exist in this application.


Also i cant iterate trough the single records while editing a "main form record". So I get only access for the first one:
  1. input.main_form.blank_subform.some_field = newValue;
Solutions for the deleting problem or the iterating problem a very much appreciated.

Best Greeting
