In order to use optional UDF parameters, you must not specify them in
the function declaration. See below:
function sayHello(first) {
var last = "";
if(arrayLen(arguments) gte 2) last = " " & arguments[2];
return "Hello, " & first & last;
}
Notice I changed your writeOutput to a return. You should always return
something in a UDF.
