HI - I'm not sure what this function is called, but I have seen other spreadsheets that are very long, and what has been done is to have a + or - button so it will expand the rows underneath. For example, Column A Row 1 would have Blue and Gold Banquet. Column B Row 1 would have the total cost from Rows 2-5. Row 2 and 5 would be suppressed underneath until that button is clicked. That way, there could only be maybe 12 rows (once completed) each reflecting a total cost, but, to drill down you can click the expansion button to show all of the subtotal costs etc? I've already received some great help on something else, does anyone have a suggestion?
