How do you show a Route in an article?

The start point 9,1

You are mistaken with separator

Good eye! I cchanged that comma to a semicolon, and turn on placemark display. Still no routes.

I see only 10 placemarks, but you enter more IDs

Placemarks have to be defined by latitude/longitude, not text address.
May be you enter HTML description with errors in html-tags.
Check have you errors on page (check console window)

Can you give me a link to your page, and I'll check, but only a little bit later, now 2:30 AM, and I've just return from vacation in Egypt

Here's the page:

g2txroadrunner.org/j25/index.php/scrapbo...-sandy-april-17-2012

The map shown does not include the entire route - hence the mismatch.

Thank you for your late-night help!

I check code, I analyse only successfull route building. I think I have to add code to check errors and show it for user, may be Google's router don't find route between points. For example, you set avoid tolls, and there is no another way, ot there is no road to place

Try one by one add placemarks IDs to route.
Ie, Set first two points. Check map. Add the one. Check...
