I have a macro that goes down row by row and checks the previous rows date.
If it is different it inserts two new blank lines. Once this is completed, I
want to sum the new columns. Using the record macro, it recorded the first
block of numbers and then copied the formula over to the next two columns.

Range("E8").Select
Selection.End(xlDown).Select
Range("E14").Select
ActiveCell.FormulaR1C1 = "=SUM(R[-6]C:R[-1]C)"
Range("D14").Select
ActiveCell.FormulaR1C1 = "Total "
Range("E14").Select
Selection.Copy
Range("F14:G14").Select
ActiveSheet.Paste
Range("H14").Select
Application.CutCopyMode = False
ActiveCell.FormulaR1C1 = "=+RC[-3]+RC[-2]"
Range("H14").Select
Range("E14").Select
Selection.End(xlDown).Select

to move down to the next block of numbers.
