Animations not working correctly

My animations are not working correctly, what I want them to do is when I'm not pressing one of the walk buttons the animation will go to the idle one. I got how to do it from some person who made a tutorial and it is sort of working. What am I doing wrong?

Here is fixed file, all you needed was to change conditions for idle stance.

Thanks!
