"end" expected to close function at line 12, but I dont know where to add the end?

The output says it needs an end but I dont know where to put it nor where it needs an end

The exact error is "end" expected(to close "function" at line 12) ner ""

Heres the code

local UserInputService = game:GetService("UserInputService")
