Dont know if this is possible. I have a spreadsheet where cell A1 contains a value which is not fixed and can change daily, the value can increase and decrease. At present at each month-end I manually record the position of cell A1 at month end in cells C1 through C12 repsenting the 12 months of the year.

Example:
A1 @ 31/01/07 = 50 therefore cell C1 = 50
A1 @ 28/02/07 = 45 therefore cell C2 = 45
and so on for 12 months

what I would like to do is automate this process to automatically capture the value at month end into cells "c" and once captured, the figure to remain absolute for that cell/month and to ignore changes in Cell A1 that may subsequently occur.

Could this be done by date formula?
