[KEYDOWN TEST] I need help. What's wrong with the slur of code?

So, I don't see any mistakes, neither does the output say anything wrong. I am totally confused.

s = game.Players.LocalPlayer:GetMouse()

s:connect(function(key) key = key:lower() if key == "g" then local f = Instance.new("Part", workspace) f.Anchored = true f.CanCollide = false f.Position = Vector3.new(0,0,0) for i = 1, 500, 0.1 do wait(0.1) f.Size = f.Vector3 +1 end end end)

s = game.Players.LocalPlayer:GetMouse()

s:connect(function(key)
	key = key:lower()
	if key == "g" then
		local f = Instance.new("Part", workspace)
		f.Anchored = true
		f.CanCollide = false
		f.Position = Vector3.new(0,0,0)
		for i = 1, 500, 0.1 do
			wait(0.1)
			f.Size = f.Vector3 +1
		end
	end
end)

The first error you have in this script is you didn't include an event!

On line 3:

s:connect(function(key)

So here it is.

s.KeyDown:connect(function(key)

Also, what's the purpose of the for loop in lines 10-13?

for i = 1, 500, 0.1 do
	wait(0.1)
	f.Size = f.Vector3 +1
end

This will certainly error out, since you're not adding 1 to really anything. Vector3 will not be a member of f.

If you want your part f to expand by 1 stud on all 3 axes every tenth of a second, try this instead:

for i = 1, 500, 0.1 do
	wait(0.1)
	f.Size = f.Size + Vector3.new(1, 1, 1)
end
