Script only working one time?

Help and Feedback Scripting Support
#1

I made this script to apply an catalogue item ( ID = id of catalogue item) to an player but somehow this script just works when never any other shirt was applied to the player since he joined the game as soon as I change the player shirt this script doesnt works anymore it just wirks on the very first change how can I fix that ? ( no error codes )

local InsertService = game:GetService("InsertService")
local item
local character 

game.ReplicatedStorage.Clothing.ApplyCustomShirt.OnServerEvent:Connect(function(player, ID)
	character = player.Character or player.CharacterAdded:Wait()
	local success, errorcode = pcall(function()
		item = InsertService:LoadAsset(ID)
	end)
	
	if success then
		if item:FindFirstChild("Shirt") then
			if character:FindFirstChild("Shirt") then 
				character.Shirt:Destroy()
			end
			item:FindFirstChild("Shirt").Parent = character
			
		end

	else
		print("Error " .. tostring(player) .. " " .. errorcode)
		game.ReplicatedStorage.Clothing.ApplyCustomShirt:FireClient(player, errorcode)
	end
end)

InsertService imports assets into models, so get the shirt out of the model and into the player, rename it to “Shirt”, and delete the empty model

In this case, I think the script stops at the character.shirt:Destroy() line, so put the item:FindFirstChild(“Shirt”).Parent = character in the same line
