How to lock camera y-axis so it only moves forward?

Hey, would you be able to post a couple of screenshots of the second part of this process (in the character blueprint)? I have the Camera Rig blueprint selected in Spawn Actor From Class, and a custom event hooked up (Event BeginPlay is in use already), but I’m not quite sure where to go from there. I’m also not sure how to create a variable referring to an actor?
