Re: "Directions"

I don't know why you are using the "arbitrary directions" code, why not
use the get directions example Mike Williams has on his tutorial:

The following example entitled "Conventional programming - Get
Directions" shows how to add the "Get Directions" buttons to the
infoWindows:

I'm not sure why window.open isn't working for you, but your page is
not very good html (you have lots of junk at the end, not that that is
necessarily causing the problem you are reporting). The markers don't
display in Firefox (but it doesn't report errors, although you still
have the error handling disabled). Opera displays the markers but
gives the following error message:

I would suggest starting from a simple case so you can determine why it
isn't working.
