Sprite Animation Walk help?

[Sansypants]

Hi. So i'm very new to Sprite Animation, and i found a very good tutorial online on how to import sprites and make the characters do their actions. The problem is that he stopped making the tutorials. So, the thing i need help with making Mecha Sonic here move from one side to say, the middle of the screen. I've tried making a motion tween after selecting all the frames, but that doesn't work. (look at attached video as example) 

If you wanna know how I imported the sprites, here is the link :https://youtu.be/Y0BPC9YXlkA

Maybe my method had something to do with it?

Prehaps i can help you, i have limited experiance in sprites.
To make sprite walk add walk loop in graph symbol and stack it on top of each other, keyframe it and space it out per your fit.
After that place the sprite walk/run loop on your main timeline and classic tween it per your needs. That is how in the nutshell sprites works, most of it is in graph symbols and after that you tween it to your desired effect, ofc you will have to do some stuff by hand like fights, grabbing stuff and similar.
This is to my extend how i can help you, if you have any other questions please ask.

Hey! I hope you have some patience as i'm also pretty new to the program and have only used it a few times outside of 1 highschool class i took where we learned how to animate stick figures. 

I'm not sure where/how to add a walk loop, and what you mean by stacking it ontop of eachother. If you could record a short video/give screenshots, or just type it out, that'd be so appreciated. I'll keep playing around with this, maybe i'll find it. Thank you.

I have. He goes way too fast without explaining fully what he's doing (in terms of walking/moving his sprite.) Especially since i'm new to sprite animation, and semi-new to the program.
