How to make a player transform upon saying a word?

So what I did was I tried making a SSJ script, the purpose of it is to transform your Roblox Character into this super saiyan with powers. It is suppose to change the Player's Shirt, Pants, and Accessories. Basically everytime I say "SSJ" it is not allowing players to transform. Any advice anyone? (Yes this is a previous one)

jun = script.Parent.Parent
Stuff = false
--password
function ssj()
if Stuff == false then
Stuff = true
for u, c in pairs (jun.Character:GetChildren()) do
if c.className == "Accessory" and c.Name ~= "Swordpack" and c.Name ~= "GlassesBlackFrame" then
c.Handle.Transparency = 1
end
end
Hair23 = Instance.new("Part")
Hair23.Parent = jun.Character
Hair23.Name = "Hair"
Hair23.formFactor = "Symmetric"
Hair23.Size = Vector3.new(1, 1, 1)
Hair23.CFrame = jun.Character.Head.CFrame
Hair23:BreakJoints()
Hair23.CanCollide = false
Hair23.TopSurface = "Smooth"
Hair23.BottomSurface = "Smooth"
Hair23.BrickColor = BrickColor.new("Bright yellow")
Weld = Instance.new("Weld") 
Weld.Part0 = jun.Character.Head 
Weld.Part1 = Hair23
Weld.Parent = jun.Character.Head 
Weld.C0 = CFrame.new(0, 0.12, -0.1)*CFrame.fromEulerAnglesXYZ(0, 0, 0) 
Mesh = Instance.new("SpecialMesh")
Mesh.Parent = Hair23
