Is it possible to keep a running total in a summary worksheet, while deleting previously entered information from the data input worksheet? For example, worksheet 1 is the data entry worksheet. Worksheet 2 is the summary worksheet. Cells A1, B1, and C1, have been used on the data input worksheet 1, and populate cell D4 of the summary worksheet, worksheet 2, with a total of 4. Is it possible for me to re-use A1,B1, and C1, with a diffferent set of data, a total of 3, for example, and have the summary worksheet not lose the previous total of 4 and add 3 to have a new total of 7 in cell D4? Formula? VBA code? Function?
