Hi! Thanks for any help....I'm using CA4 pipeline, I'm trying to follow this video at 7:40 - https://www.youtube.com/watch?v=kN-mKg5KlmM  He selects and bone and adds the new sprite.....but when I click the hand bone it won't go blue and there is no option to add the new sprite. All other bones have performed as per the video...ie go blue when I click and the '+' option appears to replace the sprite.       

Also the hand is not in the arm layer like his....maybe that's something to do with it. Can anyone help, Please I'm begging you...I've spent hours trying to add the hands!!! Thank you so much in advance animator friends
