player animation issue

hey guys, I started following a tutorial

But I got into trouble in the beginning, first episode exactly. everything seems fine in youtuber project,
but many have problem like mine and have left comments.
while everything seems ok in animator window, but player animation stuck in idle mode when running.
i uploaded the project so you guys can check it, it's a simple project. please help me, so i can share this page there for other guys with this problem.
