Why can I not add hats to this script. It always gives me a nil value?[Solved]

I have a script and it adds shirts and and pants to the character, along with a weapon. But everytime I try to add a hat or a accessory it says it not part of folder, even know it is.

Heres the script, if anyone could help that would be great :)

local classHandler = game.ServerStorage.ClassHandler
local clothingStorage = game.Workspace.ClothingStorage
local changeOutfit = game.ReplicatedStorage.ChangeOutfit

function setClass(class, player)
    local char = player.Character

  	-- Makes your class Santa
    if class == "Santa" then
        local folder = clothingStorage.Santa 
        
        if char:findFirstChild("Shirt") then
       		char.Shirt:Destroy()

		elseif char:findFirstChild("Pants") then
        	char.Shirt:Destroy()

		elseif	char:FindFirstChild("Accessory") then
			char.Accessory:Destroy()
        end
    
        folder.Shirt:clone().Parent = char
        folder.Pants:clone().Parent = char
    
        local weapon = game.ReplicatedStorage.Thompson
        weapon:clone().Parent = player.Backpack

	-- Makes your class Snowman
	elseif class == "Snowman" then
		local folder = clothingStorage.Snowman
		
		if char:findFirstChild("Shirt") then
       		char.Shirt:Destroy()

		elseif char:findFirstChild("Pants") then
        	char.Shirt:Destroy()

		elseif	char:FindFirstChild("Accessory") then
			char.Accessory:Destroy()
		end
		        
		folder.Shirt:clone().Parent = char
        folder.Pants:clone().Parent = char

		local weapon = game.ReplicatedStorage.PumpShotgun
		weapon:clone().Parent = player.Backpack
	
    end
end

function changeOutfit.OnServerInvoke(player, class)
	local value = classHandler:findFirstChild("Player_"..player.UserId)
    
    if value then
       value.Value = class
    end
  
  	setClass(class, player)
end

game.Players.PlayerAdded:connect(function(player)
    
    -- This stores which class the player has currently selected
    local value = Instance.new("StringValue")
    value.Name = "Player_"..player.UserId
    value.Parent = classHandler
    
    player.CharacterAdded:connect(function(char)
        setClass(value.Value, player)
    end)
end)

game.Players.PlayerRemoving:connect(function(player)
    local value = classHandler:findFirstChild("Player_"..player.UserId)
    
    if value then
       value:Destroy()
    end
end)
