How can I use the A and D keys to allow my character to walk to the sides?

I experimented with Owen blueprint from the animation content samples…

But when trying to copy his anim blueprint content into my own blueprint, my character gets crumbled into a ball or something…

Looking at his blueprint i can see he has 2 skeleton meshes one is called bone-modifier or something i don’t remember? And replacing them both with my own or deleting one of them don’t work…

I can’t believe nobody knows how to setup this?
