Problem with bones

I have a sligh problem with bones. I am trying to add more bones to this character I am animating. He already has some bones but when I add some more and try to make a parent, it says Error Bones Loop or something like that. Can someone help?

Gracias

A Loop is when a parent and child already exist and you try to make the child the Parent of the existing parent. It shouldn’t happen when you add a new bone but I don’t know what it is you’re doing.

If you want to add a bone to a chain then goto Edit mode and select the tip or base of an existing bone and hit E to extrude a new bone. If you want to add a lose bone then put your 3D cursor where you want the base to be and hit Spacebar, Add, Bone.
