How to duplicate character with a server script?

I need to duplicate a specific character with a server script but when I use clone and chose parent it says attempt to index nil with 'Parent' how would this be done?

You need to first say:

local Character = --Define the character
Character.Archivable = true --Makes you able to clone it.

local pl = game.Players['YourName']; --Change "YourName" to your Player's name

if pl and pl.Character then
    local c = pl.Character;
    c.Archivable = true;
    local clone = c:Clone();
    clone.Parent = Workspace;
    clone:MoveTo(Vector3.new(0,0,0));
end
