im having this issue on the line 46 how can i fix?

local Active = false
local HitNumber = 0
local DebrisService = game:GetService("Debris") --Literally the least efficient way to do this but I couldn't figure out anything else :/
game.ReplicatedStorage:WaitForChild("SwingEvent").OnServerEvent:Connect(function(player)
	local char = player.Character or player.CharacterAdded:Wait()
    local humanoid = char.Humanoid

	attachment1.Position = Vector3.new(0,0,0)CFrame.Angles(5, 5, 5)
	local trail = player.Character.Sword.Sword.TrailSkill
	trail.Attachment0 = attachment0
	trail.Attachment1 = attachment1
	delay(1,function()
	attachment0:Destroy()
	attachment1:Destroy()
	end)
	end)

		local swinganim = Instance.new("Animation")
	swinganim.AnimationId = game:GetService("ReplicatedStorage"):WaitForChild("SwordConfiguration").Swing2.Value
	local swinganimtrack = player.Character.Humanoid:LoadAnimation(swinganim)

	Active = false
	for i,v in pairs(game:GetService("ReplicatedStorage").HitVals:GetChildren()) do
		v:Destroy()	
	end
end)
