I've now tried everything I can think of, and more, ( execute PHP in a block from Google ) and it simply doesn't work.
Trying to pull users from a D6 database called drupal-test and put them into the default database called D7
Apparently, much, much more detail ( which lines in page.tpl.php ? ) is needed in the explanation of how to make the script execute, and how to tell if it can access the second database ?
Great idea that would make my life much much easier *if* it worked for me.
