Sorry if this is a crosspost. (Excel 2003)

I have the simplest of formulas to give me the time until an event takes
place. In one cell I have the now function ( =now() ). In another cell the
date/time of the event. In a third cell the event date/time-now formula
(formatted h:mm:ss). It works fine but I have to hit F9 to recalculate.
Can I get it to display a constantly updating time showing the seconds
ticking away? Also how can I get it to show the months and days away an
event is in addition to hours/min/sec?

Thanks... Bob
