Hi , Thank you to your guide but I have a problem. How can I work with these buttons now? How can I make them “interactible”? Thank you so much Lorenzo ---

I feel a little bad resurrecting a necro thread, but it’s such a good post, I don’t mind that much! I’m trying to retrieve values in variables assigned to the dynamic objects (the buttons). However I can’t seem to properly reference back to my main blueprint (which is not my character BP). When I try to reference back to my “characterSheet” BP, the node asks me for another target (what the heck?!). Humor me if you will: 1. I have an array of IDs ( **WPs** ) which I am parsing out any that repeat in a second array of IDs, just to ensure duplicating isn’t possible. 2. After that I pass the ID(s) as a Name to a table look-up, create an instance of the widget button/text, assign an ID to that button, set the text value, and return to the rest of the loop 3. The loop repeats after I assign the button as a child to a Vertical Box element in the main UMG BP. 4. I have verified everything works properly up to point, as I’m able to see the buttons and text populate the screen as I desired, and when I click one, I can “PrintString” to the screen and verify the ID is correct. So the question is: How do I get the value “ClickedButtonIDPublic” back to the “CharacterSheet” BP? I feel like is so stupidly obvious, but I’m hitting a brick wall. ---

Update: I got an answer to my question. I didn’t understand the proper application of event dispatchers. I do now. Yay. ---

Hello ! First thank you for tutorial, so helpful ! Forgive me if my question is stupid, but I am new to UE… When creating addlistitem (checkboxes in my case) I need to add another data (visibility). I tried to nest a loop, create another function but nothing worked… Where am I wrong ? ![56d6b76f8fd4b1bbe2dd18a028f369051d96a562.jpeg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/5/6/d/56d6b76f8fd4b1bbe2dd18a028f369051d96a562.jpeg) ![b17e2e6ca70382827057a267f187699fbf899f11.jpeg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/1/7/b17e2e6ca70382827057a267f187699fbf899f11.jpeg) Thank you in advance ! ---

OK someone told me how to do: use an array of a struct ![c5d4170b72bc70b6719d82f89ce1ce52d7680bd0.jpeg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/5/d/c5d4170b72bc70b6719d82f89ce1ce52d7680bd0.jpeg) ![71d2c5a18cb419de21c1f7a45817999a8d0d486e.jpeg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/1/d/71d2c5a18cb419de21c1f7a45817999a8d0d486e.jpeg) ---
