Displaying a string result from actors after click to a widget

Hi Good people. My first post - only because I’m going bald working this out.
I’m very new to UE4, so this could be something really simple I’m just missing.

I have four actors and I would like them to display a random variable from an array to a widget on my character HUD with a nice animation effect after being clicked.
I have the array and result displayed on the UI working within the Blueprint of one actor.

I’m just really struggling to work out on how to add the other three. I’ve tried adding the onClick events and input to the Level Blueprint but the Widget on my HUD doesn’t read from the Level Blueprint.

My Widget has the Blueprint below:

I’m having difficulty knowing where or which Blueprint the OnClick and Array items should be, as each blueprint I’ve tried doing it in runs into some sort of problem.
I’ll have to relay my other problem in another post as I’d be happy to get this working for the moment.
I hope this helps explain and hopefully someone could be so kind as to assist me.
Thank you in advance.
