Move 2 actors relative to eachother

I have a parent and child actors, my first person player has a child actor which is an HMD locomotion Pawn. While previewing my game If the first person character actor moves then so does the HMD locomotion Pawn relative in space, I want to make it so if the HMD locomotion Pawn Moves the first person character also moves relatively in game

Please let me know what I’m missing,

Thank you,

Melissa.
