paste flipped pose problem

I am work through the Gus tut. In part 2 I ran into a problem when I copy the pose and the go to frame 21 I click paste flipped pose it gos way off the hands are right but the legs aren’t if I paste pose THEN paste flipped pose it’s closer but still off. What am I doing wrong?

Are all your (animated) bones keyed in frame 1, and are they all selected before you copy them to the clip-board?

yes they are. Same thing for all the frames I need to copy. It comes out looking kinda like the pose that was appering on the frame I want to paste to.

here dude
watch my tut

no help I give him and stuff from the wiki the paste isn’t working
