How do I attach a paper flipbook to an in-game object, to be played after n seconds?

Hello

I’m new to UE4 and have the following situation.

On play, I want the view to be on one flipbook (Grey). I have a second one (checks) that I want played after a certain amount of seconds, for a set amount of seconds.
I want this all to loop.

I have the following blueprint, and in-game setup, but so far it is not working. Any help would be appreciated. I also apologise if this is a repeat q.
