What are my mistakes with these 2 scripts, client & server, work together - They are Remote Events?

This Is My Client Script:

local event = game.ReplicatedStorage.EarthEvent

function leftClick(mouse)
	print("Earth Element Button Clicked")
	event:FireServer()
	print("Earth Event Fired")
end

script.Parent.MouseButton1Click:connect(leftClick)

This Is My Server Script

local event = game.ReplicatedStorage.EarthEvent

event.onServerEvent:Connect(function(player)
	print("Recieved Earth Event...")
	script.Parent.Band.Handle.Transparency = 0
	script.Parent.Band.Handle.BrickColor = BrickColor.new("Bronze")
end)
