How do i make a tool that can play two animations?

so im making a game and i want it that when i click the first animation will play and when i click again the second one will play then if i click again it will play the first one again, you get it

tool/animation script

Remotes:WaitForChild("SwordSlash").OnServerInvoke = function(player,tool,SAnimation)
	
	local char = player.Character
	local Hm = char:WaitForChild("Humanoid")
	local rp = char:WaitForChild("HumanoidRootPart")
	
	local HitBox = tool:WaitForChild("HitBox")
	
	local CanAttack = tool:WaitForChild("CanAttack")
	local SwordOut = tool:WaitForChild("SwordOut")
	local CoolDown = 0.5
	
	local AttackName = "Katana Slash"--You can Rename this one
	local AttackDamage = 10
	local Length = 1--How long it will last
	local Speed = 20--How fast the move is
	local randomSlash = math.random(1, 2)
	
	if randomSlash == 1 then
	SAnimation.AnimationId = "rbxassetid://4874743902" --, rbxassetid://4871586095
	local Track = Hm:LoadAnimation(SAnimation)	
		
	if SwordOut.Value and CanAttack.Value and Track.Length ~= 0 then
		CanAttack.Value = false			
		local Bv = Instance.new("BodyVelocity")
		Bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
		Bv.Velocity = rp.CFrame.LookVector * 5
			
		Track:Play()			
		wait(0)
		GlowSword1(tool,true)
		Bv.Parent = rp
		Debris:AddItem(Bv,0.7)
		
		local ATouch = HitBox.Touched:Connect(function(hit)
			DamageTarget(char,hit,AttackName,AttackDamage,0.2)
		end)
			
		wait(0.3)
		ATouch:Disconnect()
		GlowSword1(tool,false)
		CanAttack.Value = true
		wait(CoolDown)
	end
	
	elseif randomSlash == 2 then
	SAnimation.AnimationId = "rbxassetid://4871586095" --, rbxassetid://4871586095
	local Track = Hm:LoadAnimation(SAnimation)	
	
	
	if SwordOut.Value and CanAttack.Value and Track.Length ~= 0 then
		CanAttack.Value = false			
		local Bv = Instance.new("BodyVelocity")
		Bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
		Bv.Velocity = rp.CFrame.LookVector * 5
			
		Track:Play()			
		wait(0)
		GlowSword1(tool,true)
		Bv.Parent = rp
		Debris:AddItem(Bv,0.7)
		
		local ATouch = HitBox.Touched:Connect(function(hit)
			DamageTarget(char,hit,AttackName,AttackDamage,0.2)
		end)
			
		wait(0.3)
		ATouch:Disconnect()
		GlowSword1(tool,false)
		CanAttack.Value = true
		wait(CoolDown)
	end
	return false
end

heres the click script ignore the other ones it should be named ****Attack

local UserInputService = game:GetService("UserInputService")


local tool = script.Parent
local SwordAnimation = tool:WaitForChild("SwordAnimation")
local Remotes = tool.Remotes
local CantAttack = tool:WaitForChild("CanAttack")
local SwordOut = tool:WaitForChild("SwordOut")


local Attack = false
local Attack_1 = false
local Attack_2 = false
local Attack_3 = false
local Attack_4 = false


tool.Equipped:Connect(function()
	Remotes:WaitForChild("SwordEqRE"):FireServer(tool,true)
end)



tool.Unequipped:Connect(function()
	Remotes:WaitForChild("SwordEqRE"):FireServer(tool,false)
end)

UserInputService.InputBegan:Connect(function(input,Processed)
	if not Processed then
		if input.UserInputType == Enum.UserInputType.MouseButton1 and SwordOut.Value and CantAttack.Value and not Attack then
			spawn(function()
				Attack = true
				Attack = Remotes:WaitForChild("SwordSlash"):InvokeServer(tool,SwordAnimation)
			end)
		elseif input.KeyCode == Enum.KeyCode.Q and SwordOut.Value and CantAttack.Value and not Attack_1 then
			spawn(function()
				Attack_1 = true
				Attack_1 = Remotes:WaitForChild("WaterWheelRF"):InvokeServer(tool,SwordAnimation)
			end)
		elseif input.KeyCode == Enum.KeyCode.E and SwordOut.Value and CantAttack.Value and not Attack_2 then
			spawn(function()
				Attack_2 = true
				Attack_2 = Remotes:WaitForChild("WaterfallBasinRF"):InvokeServer(tool,SwordAnimation)
			end)
		elseif input.KeyCode == Enum.KeyCode.R and SwordOut.Value and CantAttack.Value and not Attack_3 then
			spawn(function()
				Attack_3 = true
				Attack_3 = Remotes:WaitForChild("ConstantFluxRF"):InvokeServer(tool,SwordAnimation)
			end)
		elseif input.KeyCode == Enum.KeyCode.F and SwordOut.Value and CantAttack.Value and not Attack_4 then
			spawn(function()
				Attack_4 = true
				Attack_4 = Remotes:WaitForChild("DeadCalmRF"):InvokeServer(tool,SwordAnimation)
			end)
		end
	end
end)

If you'd like to make something alternate between two options, you could use a boolean value. It could look something like this:

local FirstAnimation = true

function PlayAnimation()
	if FirstAnimation then
		FirstAnimationTrack:Play()
	else
		SecondAnimationTrack:Play()
	end
	FirstAnimation = not FirstAnimation
end

If you implement something like this into where you play animations, every time you play an animation, it will switch, because FirstAnimation alternates between true and false.
