I have a spreadsheet that tracks instruments and their calibration due dates.
I'm trying to figure out the best way to do this. I want the caibration due
dates to stand out so I know at least one week prior that certain instruments
should be calibrated. I thought of setting up columns for Instrument, Serial
No., Calibration Date and Calibration Frequency. Then set up a calculated
column to calculate the due date. Then use conditional formatting to flag
the instruments that are due. This list could get long. How can I automate
this even more? Maybe set up a way of filtering out the instruments that are
due with a macro. This list will get out of control over the years if I
don't organize it well. Any suggestions?

My boss wants me to just use Excel and not Access. I'm just thinking ahead.
I know some people will tell me to use Access.

Thank you, Karen
