Why wont my scripts body height prevention work?

This is the code:

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:wait()
local Humanoid = Character:WaitForChild("Humanoid")
local BDS = Humanoid:FindFirstChild('BodyDepthScale')
local BWS = Humanoid:FindFirstChild('BodyWidthScale')
local BHS = Humanoid:FindFirstChild('BodyHeightScale')
local head = Humanoid:FindFirstChild('HeadScale')
if BHS == 1 then end
script.Parent.MouseButton1Click:connect(function()
    BDS.Value = BDS.Value - .05
    BWS.Value = BWS.Value - .05
    BHS.Value = BHS.Value - .1
    head.Value = head.Value - .03
end)

The only part that doesn't work is the "if BHS == 1 then end" This is there in order to keep the player from making himself shorter than 1, however, it will not work. Was wondering if anyone could help me out, please and thank you!
