Sorry if this is a repost...my post lost connection.

I need to change the format of cells that are changed in a range. One person
sets up the sheet and another continues it. My supervisor wants to know if
any changes have been made by the second (or third) user. We do not use a
login to the workbook and who changes it is not important, just the knowledge
that it was changed from it's original input.

I'm a novice programmer so be gentle...I understand code, just don't have
the hours in yet to be a master like you follks.
