Need some small Help with movement. New to unreal

I am fairly new to the unreal engine so i was wondering if anyone could help my with my issues. Right now i am working within the sidescroller template and am trying to allow my character to move on all 3 axes. I made a new InputAxis and tried to use that to allow my character to move forward and backward, but instead my character just turns in that direction instead of actually moving. Is this a limitation of the sidescroller game mode, or is it something i am doing wrong? I have a background in java coding so i understand most coding stuff i am just not used to how unreal works since i started using it about 4 days ago.

Here is my code and stuff
