Hi Eric,

The key thing to remember is that backScripts cannot
use the functionality of scripts that are 'lower' in
the message path hierarchy -- so it can't access
frontScripts, card scripts, or the scripts of stacks
in use. It can only use the ones that are 'higher'.
So if the revdb library is loaded 'below' your script
at runtime, it can't call its functions. In the dev
environment, a slew of backScripts are loaded first ;
perhaps this isn't the case in a standalone.
Is there a reason why it's a backScript and not just a
stack that you start using ? Then it would work just
fine (99% probability).

Hope this helped,

Jan Schenkel.
