[Maya] Sugerencias error mel 166

Hola, he estado probando de unir los huesos con la Maya de muchas maneras, pero siempre me salta este error de mel.166 (y entonces no me deja unir-lo)alguien sabe por que y cómo puedo arreglarlo?
Estoy aprendiendo Maya así que, lo siento es es una tontería, pero no hay manera qué lo arregle.

Aquí os dejo imágenes por si me he explicado mal.
