Im trying to rig a character with the Quick rig option in Maya LT. It works well but doesn't come with a hand with fingers so I created one. I have two issues, the first is that I cant mirror the joints I made, it tells me I have too many arguments, not sure what that is. Secondly I want to add these bones to my rig so that I can add the mesh to my skinning of the model, but it says :is already connected to a skinCluster.
Here is a picture of the issue
