Trouble with Camera bob and Player movement

I’m still new to using the blueprint system in UE4, but I’ve been trying to set up a camera bob effect based on what I’ve found in other posts. What I’m trying to do is make it to where the bobbing effect works when the player presses W,A,S, and D as basic movement controls. With the way my blueprints are set up, the bob effect works fine when W (forward) and D (right) are pressed but it won’t work with A or S.

I’m wondering if it’s because the scale for these inputs in the project settings are both negative values, or it could be that my blueprints are just wrong. I’m not really sure. If anyone has advice that would be excellent. Thanks!

I’m attaching a picture of the bob blueprints for when the player moves right and backwards. They are the exact same but backwards does not work. 43f749cda2190b1fb9cd8b8ba5db0322cbff9a15.png
