script.parent.Touched script not functioning?

I have seen numerous guides on this, and everyone says to use script.parent.touched , but for an unknown reason to me, in the dev console with the output, it does not show a print statement I put in the function. Please help!

Add this script to the part.

local part = script.Parent

local function onPartTouched(otherPart)
	local partParent = otherPart.Parent
	local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
	if humanoid then
		print:("lol work coolio")
		--game.Lighting.Blur.Size = 843748673958
	end
end

part.Touched:Connect(onPartTouched)

Honestly not sure why this is happening for you, but maybe you made some small error that's unnoticeable. Maybe try copy-pasting the code above this answer or the one I put below to see if that works

local part = script.Parent

part.Touched:Connect(function(touched)
	print('Works')
	--add whatever here
end)

--If you want to locate the character that touched it
part.Touched:Connect(function(touched)
	local hum = touched.Parent:FindFirstChildOfClass('Humanoid')
	
	if hum then
		print('pog')
		--add whatever here
	end
end)
