Loop animations in animator component?

I have an Idle and Walk state for a zombie.

The animator controller looks like this:

Entry----> Idle<===>Walk

Firstly, I can't figure out how to loop the Idle, it only plays once then the zombie freezes.

Secondly, when the condition is met so the Walk animation is played, it only plays once, then goes back and plays the Idle animation.

Sorry if this is unclear, feel free to ask me questions. Thanks in advance.

EDIT: Solved! I had to open the animation itself in the Inspector window and check off "Loop Time" and "Loop Pose!"
