How do I compare object variable from family?

In my quiz game, I have 4 buttons each representing an answer. All 4 are in a family.

When I click the correct answer, it changes frame for that clicked button. Same happens when you click wrong answer and it shows different frame.

Now I am trying to also switch frame for the correct answer when you click on the wrong answer at same time but have not been able to crack it.

Tried using the pick from family and comparing the family ID variable against the correct answer ID variable but it does not work as I think it only picks the ID of the clicked button.

Ah never mind, just cracked it now. Had to use pick from individual buttons and do the check rather than from the family and that works now.
