Gameplay mode W & S keys not working for forwards/backwards

Hi all,

Need assistance troubleshooting something I’ve been trying to resolve for most of the day. I wanted to add in footstep sounds to my first person character during gameplay moder which i have successfully completed however now when im in gameplay mode the W and S keys will not let me move forward and backwards. Refer to attached Blueprint for my first person character.

Could someone please advise the best way to resolve this so these keys will work in gameplay mode?

Thanks,

Georgia
