I need help with Relative Rotation

Here is a picture of my blueprint! I need help to figure out what the target is and how to add it! Thank you!

If you want to set rotation of the entire actor, use SetActorRelativeRotation.
SetRelativeRotation is used for components only. If you hover over the Target pin, it’ll show you what king of target it’s looking for.
P.S. Bind Event to Swap need a target too.
