Is it possible where you are passing this value, you could pick template as the type of input and put your new lines in there?
One solution would be to use a script step.
The discussion list showed this post as from 2 days ago even though it is over 3 months old.
regarding the "add new line!" see forum:
I tried many different options, and the most consistent was to go the executeScript way.
Make a resuable component or something like that.
hope it helps...
I was answering the question, not looking for additional info. Steve is short for Stephen.
