--this is how you comment
--Lua cares about case but not whitespace
--function starts an action, p ends it
--functions can be local or global (in front of p={}), and if you don't write either, defaults to global
--task 2: name=}} isn't an empty string! lua only recognizes a completely missing parameter as an empty string
