For multiple workbooks, you need to add to each.

OK, I want to monitor 2 ranges; F3:F40 , if any one of then = "PM Service"
then I want to use value in corresponding cell in range C3:C40, then add
set
value 15000, when value in Range C3:C40 reaches that total value I want a
popup reminder that it is "Time for an oil change". This will need to work
across multiple workbooks, I hope.

I use an excel workbook to keep track of trips (mileage, stops,
fuel,
oil
changes, ect....). I want to creat a popup notification for oil
changes
that
monitors a range of cells and pops up when mileage is reached. I
created
the
workbook myself and always trying to improve it.
