can I use excel to select a range of values and sum them together based on the header of the column and the rows have certain values for example I want to find the sum of the cells from column(Station_Count A02) but I only want the sum of the all the values for the range that starts with 6 the eg (6:30-6:55) and so forth tried using index match but I'm missing something in the formula to grab the correct ranges.
