This is what I've tried:

function Click(What)
print(What)
end

script.Parent.MouseButton1Click:connect(Click(1))

Here is the errors:

--Wont post my time here :D

Loaded gloo library. Type _G.gloo.Help() for help.

Ok when I click it:

00:00:00 - attempt to call a nil value

I put 00:00:00 there because I do not want you to know my timezone.
