Change player turn axis?

Hello everyone! I am down to the (hopefully) final step in my blueprint only directional gravity system. I need to change the axis on which the character rotates when turning around. Currently when I set the gravity to a horizontal force the player can only move forward. This is because when they would turn left, right, or backwards they turn along the z axis instead of the x or y (depending on the direction). When they do this, their feet leave the wall and they fall off. If they were to turn along the correct axis their feet should stay on the wall. Does anyone know how to fix this? I believe this is the last step before I can start working on extra features. Thanks in advance!
