I can't get a second walk cycle to work

I was able to make a walk cycle. Then I wanted to make another walk cycle. In the Dope sheet, I moved the keyframes for the first walk cycle over to the right (g-x). Then I made a new action. Then I inserted my keyframes for the new action. But it doesn’t play when I press alt A. Can someone tell me what I am doing wrong?
