Changing players Flipbook via Blueprints

Hey guys

I am fairly new to the world of unreal and trying to make a small game for a game jam going on but I am having an issue with having the players Flipbook changing once in a certain trigger volume I have made. I have not adapted much from the original example blueprint for 2D character movement.

What I am trying to do is have 2 forms of the players character, one when stadard sprite set (which has been set up and is working fine using the example blueprint) but when the player enters the trigger I have made I am looking to have it switch to a different flip book until the player leaves that area.

I m not sure what anyone might need to help me, but any help would be fantastic !
