Faucet onClicked Script help?

In ROBLOX Studio, I was editing a faucet to make it dispense water using trancperency changes via script and Click Detector. It said there was an error on Line 1. Please tell me what's wrong with the script.

function hotWater(onClicked)
	if script.Parent.Parent.Water.Transparency = 0.48 then
		script.Parent.Parent.Water.Transparency = 0
	end
	else script.Parent.Parent.Water.Transparency = 0.48
end

script.Parent.ClickDetector:connect(onClicked)

-- Replace your last line where you call the script to be executed to this.

script.Parent.ClickDetector.MouseClick:connect(HotWater)

-- HotWater is the name of your function and you do not need the arguments "onClicked"
