Issues with Adobe Animate Walking Tutorial

The tutorial seems simple enough.  You choose the boy trekker character, select a background, insert the keyframes, create the motion tween and then move the background to create the illusion of a boy walking.  Every time I follow the steps though, my character is walking in place as if he's on a treadmill.  I have tried Adobe products in the past but never spent much time with them because I wanted products that were less frustrating.  However, almost every YouTuber I admire tells me that they use Adobe products when I ask them what they use and so I want to stick with it this time.  Please help.
