I am trying to swap out StarterCharacters by clicking a GUI button and it is not working?

I am trying to pull the StarterCharacter from replicated storage and place it into my StarterPlayer to Change the character.

So, When I click my GUI button I get this in my output log: Players.simcity99.PlayerGui.ScreenGui.Buttons.James.Script:16: attempt to index a nil value.

I am assuming I messed up the remote event.

Here is code:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local createPartEvent = Instance.new("RemoteEvent", ReplicatedStorage)
createPartEvent.Name = "CharSwap"
 
local function onClicked()
	script["Click Sound"]:Play()
		
	local StarterChar = game.StarterPlayer.StarterCharacter
		
	StarterChar:Destroy()
	local ReplicatedStorage = game:GetService("ReplicatedStorage")
	local James = ReplicatedStorage["James"]:Clone()	
	James.Name = ("StarterCharacter")
end
 
onClicked().OnServerEvent:Connect(onClicked)

Where did I mess up?

you calling OnServerEvent on the function, you should be calling that on the remote!

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local createPartEvent = Instance.new("RemoteEvent", ReplicatedStorage)
createPartEvent.Name = "CharSwap"

local function onClicked()
    script["Click Sound"]:Play()

    local StarterChar = game.StarterPlayer.StarterCharacter

    StarterChar:Destroy()
    local ReplicatedStorage = game:GetService("ReplicatedStorage")
    local James = ReplicatedStorage["James"]:Clone()    
    James.Name = ("StarterCharacter")
end

createPartEvent.OnServerEvent:Connect(onClicked)
