Trigger Form actions based on values of selected entry in embedded view

We have a form 1 that contains some fields and a embedded view. This embedded view does show documents which are created from another form 2.

Now, we want to trigger actions on this form 1 taking the values from the selected entry in the embedded view. How can I reference from the form 1 to the values of a selected entry of the embedded view?

Thanks for your help.
