Thanks for the information. I hadn't been using 'our' or 'my' in modules, but I see from your example why I should. And the namespace qualifying as well. A bit of a task to modify the modules, but thankfully I'm not so deep into this one that it's a mountain of script to go through:)

As the old saying goes...well, how I think it should go, in this case:
"If it ain't broke, don't fix it. But just because it ain't broke don't mean it's working properly."
