I am trying to do something I'm pretty sure FF can do fairly easily, but for SOME reason (user incompetence is a high possibility...) I'm just not able to piece together an answer that works for me.

I have a form that looks great on the list view, but when I drill into the detail view I want another form to only display responses for that specific original form entry. 

I've created Form 1 with entry ID's 1, 2, 3 showing on the list view. Form 2 is placed in the detail view. Neither form currently share any fields. When I click on an entry to show the detail view, it shows ALL of form 2's responses, while I need it to "filter" (term used lightly) for the original entry ID only.

I've tried to filter the views for form 2. No go. 
I've tried to put in a hidden field in form 2 with [get param] to try to "grab" the Entry ID from Form 1 to link them, but can't figure out what param to put in to grab it.
The URL will change so, it seems like putting the URL in would only show that specific entry.
I've tried creating an autofilled field that they both share in order to nest the view, but can't get it to fill without user input.

I think I may have read and re-read every FF site related to this issue, but nothing is registering.
Have I mentioned I'm very new to all of this?
Again, it's most likely user incompetence so IF there is an easy fix could someone plz spell out the solution for me? ANY suggestion would be appreciated.

Thanks so much & plz be gentle with my idiocy...
