Why is mouse not a valid member of instance?

Help and Feedback Scripting Support
#1

I get this error for this block of code:

Mjolnir.Equipped:Connect(function(Mouse)
	LoadIdleAnimation:play()
	Mouse.Buttton1Down:Connect(function()
		LoadHammerThrowAnimation:Play()
		HammerThrow:FireEvent()
	end)
end)

Why can’t Button1Down be used for this?

#2 
Mouse.Buttton1Down:Connect(function()

What you had, look carefully at “Button”

Mouse.Button1Down:Connect(function()

Fixed version

#3 
Mouse.Buttton1Down:Connect(function()

Typo?

#4

OMG LOL, I guess it’s time to take a break, i’ve been scripting all day hahaha.
