EDIT: I've found out that my keyboard W event isn't even firing in the blueprint? Why is this?

Hey there,

I am currently running into a problem with footstep sounds. Our game has no character and is in first person.
I want a soundcue to play whenever W,A,S or D is pressed and I want to stop it when W,A,S or D is released.
I created a blueprint using the soundcue and created the following blueprint:
Soundcue BP:


Soundcue options:

I have a feeling the event isn't even firing when I press W? Am I doing something wrong? is there annother way to play a soundcue when W is pressed?

Thanks in advance,

Keesie
