Falcon Punch Help

[KingJigglypuff]

Hey, I'm trying to make Yoshi do the Falcon Punch. I replaced the standard B (both ground and air) and made all the bones normal. It works, but there's one problem, when I do the move he doesn't go forward, he goes the distance of the move, but then goes back to the staring spot.

Uh go under animation flags then click moves on.

Uh go under animation flags then click moves on.

OK, I did that, but now Yoshi does the animation in place and doesn't move at all.
