Unable to reuse my character

Hi all,

I have a problem. I drew a character then added a skeleton to it. I wasn’t happy with the result. I tried to do it all over again. Things got worse. When I tried to link the character to the skeleton, the vertices remained lit up…and obviously the skeleton and the character weren’t linked.
I duplicated my character and tried to add a new skeleton to it…Again, nothing…it’s as if my character wasn’t reusable . I tried to disconnect its parameters . Still nothing. Can anyone help by telling me what to do so I can reuse my character?

Thank you in advance :rose: :rose: :rose:
