[SOLVED] Access from a grid to a form via link application

I have a grid with the table information, and create a link to the application form_information.
The form shows only the buttons ADD and BACK.
When I access the form form_information directly, so the buttons appear ADD NEW, SAVE, DELETE and EXIT.
What did I wrong?

Link between applications - Parameters Definition.
The values that will be passed to the parameters was empty.
I have set the Field to the primary key.
Now it works fine.
