Actually, I found what you're talking about. I missed a brace.
In your
phoogle_mapcodebits template:
FIND
HTML Code:
marker{$g}{$post['postid']}.openInfoWindowHtml("$validPoints[$g]['passedAddress']}");
REPLACE WITH
HTML Code:
marker{$g}{$post['postid']}.openInfoWindowHtml("{$validPoints[$g]['passedAddress']}");
I've updated the .xml in the original post. This would only rear it's head if you didn't pass a title to the marker.
Woops! :P
