[SOLVED] Losing variable values when passed to library

@tonanbarbarian: Thanks for that. As it turns out, this proved to be the simplest problem - a typo in the DB password. Aside from my general thick-headedness, I think this is an indication that I should try and get more than four hours sleep a night. I swear I looked at the DB config file for a long time I didn't spot the difference.

You sir, are entitled to a Virtual Beverage. Enjoy!
