Why doesn't the character size change?

So I am just making a script for fun, and to practice, it is meant to turn the player into a golden giant, but I have run into a problem, It all works fine, but when I try and change the size of the player, they don't change at all, the values are updating inside of the humanoid, but it doesn't change the size of the character.

local uis = game:GetService("UserInputService")
local char = script.Parent
local pants = char:WaitForChild("Pants").PantsTemplate
local shirt = char:WaitForChild("Shirt").ShirtTemplate
local colours = char:WaitForChild("Body Colors")
local skincolour = colours:Clone()
local transformed = false
local debounce = false
local humanoid = char.Humanoid

local function gold()
	for i, part in pairs(char:GetChildren()) do
		if part:IsA("MeshPart") then
			part.Material = "Metal"
			part.Color = Color3.fromRGB(255,255,0)
			print("Changed to gold")
			if part.Name == "Head" then
				part.face.Transparency = 1
			end
		end
		if part:IsA("Accessory") then
			part.Handle.Transparency = 1
		end
	end
	humanoid.BodyHeightScale.Value = 7
	humanoid.BodyWidthScale.Value = 7
	humanoid.BodyDepthScale.Value = 7
	humanoid.HeadScale.Value = 7
	humanoid.BodyProportionScale.Value = 1.75
	humanoid.BodyTypeScale.Value = 1.75
	char.Shirt:Destroy()
	char.Pants:Destroy()
	transformed = true
end

local function normal()
	for i, part in pairs(char:GetChildren()) do
		if part:IsA("MeshPart") then
			part.Material = "SmoothPlastic"
			print("Changed to normal")
			if part.Name == "Head" then
				part.face.Transparency = 0
				part.Color = skincolour.HeadColor3
			end
			if part.Name == "UpperTorso" or "LowerTorso" then
				part.Color = skincolour.TorsoColor3
			end
			if part.Name == "LeftLowerArm" or "LeftUpperArm" then
				part.Color = skincolour.LeftArmColor3
			end
			if part.Name == "LeftLowerLeg" or "LeftUpperLeg" then
				part.Color = skincolour.LeftLegColor3
			end
			if part.Name == "RightLowerArm" or "RightUpperArm" then
				part.Color = skincolour.RightArmColor3
			end
			if part.Name == "RightLowerLeg" or "RightUpperLeg" then
				part.Color = skincolour.RightLegColor3
			end
		end
		if part:IsA("Accessory") then
			part.Handle.Transparency = 0
		end
	end
	local newshirt = Instance.new("Shirt",char)
	newshirt.ShirtTemplate = shirt
	newshirt.Name = "Shirt"
	local newpants = Instance.new("Pants",char)
	newpants.PantsTemplate = pants
	newpants.Name = "Pants"
	humanoid.BodyHeightScale.Value = 0.9
	humanoid.BodyWidthScale.Value = 0.95
	humanoid.BodyDepthScale.Value = 1
	humanoid.HeadScale.Value = 1
	humanoid.BodyProportionScale.Value = 1
	humanoid.BodyTypeScale.Value = 0.7
	transformed = false
end

uis.InputEnded:Connect(function(key)
	if key.UserInputType == Enum.UserInputType.Keyboard then
		if key.KeyCode == Enum.KeyCode.Q then
			if debounce == false then
				debounce = true
				if transformed == false then
					gold()
					wait(0.5)
					debounce = false
				else
					normal()
					wait(0.5)
					debounce = false
				end	
			end
		end		
	end
end)

Its quite a messy script, but other than the size, it works
