move character

I looked at the frequent issue post, but everytime I enter in that command it says the character cannot be found?
I am typing in
move_character <captain tiberivs> <120>,<106>

Ive tried combing the name, spelling it with a u instead of a v etc

Try "Captain TiberivsA", "...B", etc. Chances are you won't be able to move him at all if there's more captain Tiberivses standing around. They might have the same internal name.

I am actually trying to move a rebel family member but they say they cannot locate the character?

You need hyphens around the character name. Make note of the capitalization and spacing, it's "Firstname middlenameLastname".
