How to specific find "only thing" from structure array?

I have structure for my character then I want to find for “only boolean” from them
but blueprint said can’t find any of them so I hid other else except boolean but it seem not to work

Sorry man i dont understand
can you be more clear,

Why can’t anyone understand what I told
I am sure that I’m using the same language like anyone

Alright, nevermind
I finally found a resolve from somewhere else
