Dear Rocky:
I kindly suggest that when you ask about an error, you provide the following
info:
* What were you doing when the error happened?
* Were you handling a large file?
* Does the file take a long time to create or recalculate?
* Did you create the file in another version of Office?
(If you did, then microsoft states that you will have to recalculate the
file each time you open it until you save it in the Excel 2003 format)
* Does your workbook have macros?
These answers will help us find your answer more efficiently.
