Did you make the hack to the Joomla index.php file?
Also, it is possible that this will not work with CB 1.1. I don't know, I only have tested it in 1.2. CB 1.1 does not offer a delimiter field type, right?
FYI, even before I made the hack to the index.php file, I could get the plugin to pull the user's data into the tag by using the proper variable name.
In other words, I created a new delimiter field and entered {mosmap address='[cb_busstreet1], [cb_city], [cb_state] [cb_zip]'} into the field body.
Then even though my map was not working (since I had not done the hack), what displayed in the front end was:
{mosmap address='2312 Far Hills Ave.', 'Dayton', 'OH' '45419'}. So at least I knew that I had the user's field variables listed correctly.
Then after I made the hack, the map displayed too.
