Checkbox Formula between related tables

Hi there. This is the first time I've used this forum, so please excuse me if I'm violating any etiquette! And, thanks for trying to understand my poorly-worded question!

I?d like to create a formula for a checkbox field that looks into a related table to determine if it should be checked or not.

Table 1 ? ?Merch Elements?

            Table 1 field: Checkbox Formula called ?Active Merch?

Table 2 ? ?CTAs?

            Table 2 field: Checkbox called ?Active CTA?

Table 1 has a one to many relationship with Table 2: Each ?Merch Element? has many ?CTAs?

I?d like to put a formula in ?Active Merch? checkbox formula field in ?Merch Elements? that would look at all the related ?CTAs? in Table 2 and if ANY of those CTAs have the ?Active CTA? checkbox checked, then check ?Active Merch? field in ?Merch Elements?.  And, of course, if there are NO related ?Active CTA? checkboxes checked, then the ?Active Merch? checkbox should be unchecked.

In other words, I have merch elements (they look like boxes) on my website and there are several Calls to Action (CTAs) in them, like ?buy,? ?try,? ?learn more? etc. When I remove one CTA from the merch element, I don?t want to lose the data from it, I want to make it ?inactive? so I can filter it out. But, the merch element is still active since there are other CTAs still active in it. Now, If I make ALL the CTAs from that one merch element inactive, then I want the merch element itself to become inactive automatically.

I am sure I?m not being clear enough, sorry about that. Hope someone can help me.
