I have a spreadsheet with a unique identifier for each
customer, Customer Information File (CIF). Whenever this
number changes, I want to automatically insert a blank
row. This will merely making the the spreadsheet more
pleasing to the eye to read. Keep in mind, there may not
be a break in CIF for 1 to 15 lines, but whenever this
CIF number changes, I want a new blank row.

Any help would be greatly appreciated!!
