Inventory: Navigate a vertical Box Widget?

Hello! So I managed to get it but in a different way.

It’s a bit much, but basically with the controller input I gathered all the children widgets within the vertical box, and put them in an array, and assigned the current index to a variable.
That variable designates which index we are t, and therefore, the widget currently selected. I loosely based it off of a tutorial On menu widgets.

So far it works but I have to press a button twice in order to get the focus onto the vertical box before I can navigate it. So I now basically have to press up or down one more time before the cursor highlights the one I want highlighted.
