[HELP] Trying to use SoapUI JAR to make changes

Thank you for your response. Through lots of trial and error (8 hours worth) I was able to figure out how to clone an existing operation. Which is what I really needed anyways. Now I am having trouble adding an assertion. I don't get to copy this one. I am pasting all my code for any others down the road that stumble upon this thread.
