Load form within a form

[BigEfromDaBX]

I have form with a YES or No question. Is it possible to load another form with a set of questions if user hits n(No)? Please note that the form that opens if you choose N will be data in another table.

Do I have to create a behavior for this using one of the below?

App: open a form to add a new row to this table (not a row-level action)
App: open a form to edit this row

I am a noob. So If I am going about this the wrong way please let me know.

Thanks.
