Thank you again Michael.

I started a text file of a bunch of your script explanations. It is good for review and recollection.

There is no way I would ever have figured it out!

Installed the changes, and Flow does work! It took about 3.5 seconds.

Some tentative observations:
The first two links are missing...I think.
I think end selection of the target curve selection is not working either.

I think there is some cleanup to do on the script also.
Undo leaves link2 persisting...

More work to do tomorrow.

:-)
