Yes, I understand. Well, it sounds complex to add an easy-to-understand interface for such thing in a countdown script, but it's very well doable to program the functionality. Maybe I can add tags like %th for "total hours" and %ts for "total minutes", but it'd get very difficult to add functionality for "X hours and Y seconds", with Y also including the minutes.
As my script (Countdown Live) is getting pretty outdated and I don't seem to care opening those project files any soon (hey, we don't get paid for scripting, you know!
), I'm afraid you'd have to look for another script or talk to another developer if you need this really really quick. But it may be a point to think about when I'd want to resurrect my script one day.
