I'm trying to sum the total number of hours within a set of rows. I've created formulas that calculate the total number of hours based on a weighted probability. At times, totals within cells will need to be moved from month to month. The most efficient way would be to allow a cut and paste function, but when doing this the formulas get messed up. For example, the formulas in all of row 13 below are linked to the probability listed in cell B12. Cell N13 has the the following formula "=$B12N12", cell O13 has "=$B12O12", etc.
IN the below screenshot, I am trying to move the values from N12 through P12 to J12 through L12 without changing formulas in row 13.
When I do I get the #REF! error for cells J13 through L13. How do I prevent the formulas from changing? I have tried locking select cells in the spreadsheet but it doesn't resolve the problem. Please, help.
