Is it possible to make an error message with custom animations?

Hi so I was making my game and came across something which really bugged me, so in my game you have a value which is called "Cash" and you can buy stuff with it, but if you don't have enough it does absolutely nothing. I know many games use this cool error animations for example Theme Park Tycoon being one of them.

So I basically want a error message gui bar that appears at the top and when a player keeps clicking the error it scrolls down the other error you can see a good example of it in theme park tycoon. I already know how to use TweenPosition and I also know how to create a gui but I don't know how this would work. Please help.

I have already made the error animation when a player pressed the button and hasn't got enough money but everytime they press it again it just overlaps.

My code is here:

local button = script.Parent
local requiredCash = 1500 -- How much is required to buy it
local plr = game.Players.LocalPlayer
local leaderstats = plr:FindFirstChild("leaderstats")
local cash = leaderstats:FindFirstChild("Cash")

button.MouseButton1Click:connect(function()
	if cash.Value >= requiredCash then
		-- this just gives the player the stuff they need
	else
		local gui = Instance.new("ScreenGui", plr:FindFirstChild("PlayerGui"))
		gui.Name = "ErrorBar"
		local error = Instance.new("TextLabel", gui)
		error.BackgroundColor3 = Color3.fromRGB(255, 0, 0)
		error.Text = "Error | You have insufficient funds"
		error.Size = UDim2.new(1, 0, 0, 50)
		error.TextWrapped = true
		wait(4) -- delay
		for i=0, 1, 0.1 do
			wait()
			error.BackgroundTransparency = i
		end
		gui:Remove()
	end
end)

It creates a nice error but it has no animations and every time someone spam clicks it, it just overlaps and looks ugly.

You shouldn't use a variable named error, as error is an actual global function. Use, say, a variable named errorGUI.

This fx is actually really easy. Just create a boolean variable to tell whether the animation is playing or not.

local button = script.Parent
local requiredCash = 1500 -- How much is required to buy it
local plr = game.Players.LocalPlayer
local leaderstats = plr:FindFirstChild("leaderstats")
local cash = leaderstats:FindFirstChild("Cash")

local errorIsPlaying = false --new variable

button.MouseButton1Click:connect(function()
    if cash.Value >= requiredCash then
        -- this just gives the player the stuff they need
    elseif not errorIsPlaying  then --checks if the animation is playing
	errorIsPlaying = true --sets the animation variable as true, so if the button is spammed it doesn't do anything

        local gui = Instance.new("ScreenGui", plr:FindFirstChild("PlayerGui"))
        gui.Name = "ErrorBar"
        local errorGUI = Instance.new("TextLabel", gui) --You shouldn't use "error" as a variable
        errorGUI.BackgroundColor3 = Color3.fromRGB(255, 0, 0)
        errorGUI.Text = "Error | You have insufficient funds"
        errorGUI.Size = UDim2.new(1, 0, 0, 50)
        errorGUI.TextWrapped = true
        wait(4) -- delay
        for i=0, 1, 0.1 do
            wait()
            errorGUI.BackgroundTransparency = i
        end
        gui:Remove()
	errorIsPlaying = false --sets the animation variable as false, so it can be played again.
    end
end)
