Have you taken the LMCD? You might consider taking that. It would fill in a lot of your knowledge gaps.
I still think you might consider removing the carriage returns from it9. You do that with .replaceAll(“what to remove”,”what to replace it with”). So .replaceAll(“\r”,””) or .replaceAll(“\r\n”,” “) or .replaceAll(“\n”,” “) should work to remove them allowing it9 to contain the maximum number of characters allowed. Someone from LM might be able to chime in detailing what the character limit is for a property. You might have to limit that before inserting it into your println statement.
