I have 11 columns with headers. I need to insert three rows when data in columns B and C are different. Example:

Column B has a date, Column C has country code

DATE COUNTRY
9/16/2014 MAYS
9/16/2014 MAYS
9/16/2014 MAYS
9/16/2014 INDI
9/16/2014 INDI


I need the macro to insert 3 rows between the date and country

DATE COUNTRY
9/16/2014 MAYS
9/16/2014 MAYS
9/16/2014 MAYS



9/16/2014 INDI
9/16/2014 INDI

I will have a spreadsheet of multiple dates and countries in Column B and C, so need to insert rows then upon selecting macro
