My character is not moving when playing animation

Hi, I'm newbie 2D game developer.

My character is made by the following:

1. Skinning Editor

2. Bones

3. Auto Geometry

In order to move my character, I've used Input system.

When I enter play mode, I can see my character is playing 'Idle Animation' Perfectly.

But, when I try to move him using Keyboard, it plays 'Walk Animation' perfectly, but not moving.

I've looked through my code and find no error.

I've disabled the 'Animator' and my character moves perfectly without animation.

I've check the 'Apply Root Animation' button, and it gives me no help.

Please save my poor character.
