Why does this button not work? It is supposed to give the player certain clothing.

There is a button I can click, that is supposed to make the player wear certain clothing when they click the button.

Here is what I have:

function onClick(hit)
	local h = hit.Parent:findFirstChild("Humanoid")
	if h~=nil then
		local s = onClick().Parent:findFirstChild("Pants")
		if s~=nil and d~=nil then
			hit.Parent.Pants:remove()
			script.Parent.Pants:clone().Parent = hit.Parent
		elseif s~=nil then
			hit.Parent.Pants:remove()
			script.Parent.Pants:clone().Parent = hit.Parent
		elseif d~=nil then
			script.Parent.Pants:clone().Parent = hit.Parent
		elseif s==nil and d==nil then
			script.Parent.Pants:clone().Parent = hit.Parent
		end
	end
end

script.Parent.MouseButton1Click:connect(onClick)

Try Putting The script.Parent.MouseButton1Click:connect(onClick) On The Top Of The Code.
