Survival Shooter: Walking animation not working

[GSoster]

The animation configuration is correct in the Animator window, the transitions exist and are configured as they should. The code in the PlayerMovement script is also correct, still the player doesn't play the walking animation.

In the Animator Window, after clicking in the transition from idle to walking the option Has Exit Time in the inspector should be unchecked. since and animation must finish before starting another one.
