How do I make an ImageLabel Image change if a TextLabel has a specific Text in it?

I just started scripting and want to learn how to make an Image change if a TextLabel says a certain thing.

This is a LocalScript in my ImageLabel, which I thought would turn the Image into a random screenshot I had if the Text below it said 1

if script.Parent.Parent.Display.Text == 1 then
	script.Parent.Image = "https://www.roblox.com/library/11452628830/Images-actual-car-no-texture"
end

This is a LocalScript inside the ScreenGUI

local number = script.Parent.Number
local button = script.Parent.Roll
local Display = script.parent.Display

button.MouseButton1Click:Connect(function()
	number.Value = math.random(1, 2)
end)

number.Changed:Connect(function()
	script.Parent.Display.Text = number.Value
end)

Not sure what's wrong, anything helps!
