Trying to make a basic scripted python lookup. The examples and tutorials were just way over my head. So trying to do something simpler. I coped the example file and tried to simplify the problem a little. What I am aiming to do here is pass a field called 'mystring' and get back a field called 'myoutput'.
I am passing hello as the field value for mystring and expecting world as the value in the new field myoutput.
