You can do the border part without VBA by using conditional
formatting.
Select the whole range, then Format/Conditional Formatting,
formula is =MOD(ROW(),5)=0 and format of heavy underline.

Hi,
By vba, how can I
a) insert a bold black border along the top edge of every fifth row down to
about row 1000 ( and along the row to K)?
b) make every fifth cell in column K a dropdown list using data validation?

Thanks
