'Paste X-flipped Pose' doesn't work

Hi guys.

I am trying to make my blender 2.5 avatar walk but I faced a problem I couldn’t solve.
I have inserted a pose in the 1st frame and I try to copy it flipped to the 21st frame, but it doesn’t work. Only it’s legs move a little bit. I tried several solutions I found in Google, but no success. I spent several hours without any result. That’s why I am asking you to have a look at my project and tell me if you manage to do anything. Here it is:

Thank you in advance

I didn’t look at your file, everytime I have seen this problem it’s always been the same thing, bone roll angles. Please take a look at the bones in the legs, the z-axis should be pointing either forwards or backwards and the x-axis either to the left or the right. And they should match from left leg to right leg, if the left leg’s z-axis is forward, the right leg’s z-axis should be forward.

I have already set the Roll value for each bone to 0 but still nothing. Is that what you meant?

Hahaha…opps, yea that’s not the problem with your file. Your problem is that you don’t have any bones named. For this to work, the bones need to be named and with a suffix to tell blender which side the bone is one, and the names have to match. For instance thigh.L and thigh.R will work, Thigh.r and thigh.R won’t work because the names don’t match.

This was the problem, thank you very much for your time!
