Are you asking if i have two or three numbers in the column A? If so, just using the "A Phase" column as an example, the sum of column K for all two/three numbers would need to go into column C. For example the 6.9, 6.11, 6.13 row in column A would need the sum of K5, K6, and K7 to go into C11. Then the same would be done for the B and C phase (sum of columns L and M for those rows into D11 and E11). Let me know if that's not what you're asking and thanks for getting back so quickly.
