Move camera left and right fixed amounts along axis

Hello. I have a “level” where you can pick which color monster you want to play as. I have them all lined up and a camera Character set up facing the character in the middle of the line up. Each character is placed 800 X Axis units apart. I would like to have my Camera Player smoothly move 800 units to the left or right with the A and D Key.
In the World settings I have the Default Pawn Class setup as “colorpicker” the camera character basically.
I also have a color picker game mode

both of these blueprints seem to do nothing
