Unsolvable cell naming question: Can anyone beat this one?
I am trying to copy and paste named cells from one workbook to another without having the first workbook file name attach to the named cells. For example, I am copying a cell named XYZ from file One.xls to file Two.xls. I need to have cell XYZ NOT say One.xls!XYZ when it is entered into Two.xls. Also, how can I get that message that asks if I want to use the cell names to not pop up? I think I understand what you're running into here. If the cell you are MOVING refers to a named range in it's source workbook that doesn't exist in the destination workbook, Excel will not ide...

Help: Money Transfer Transaction Dates
I was using Money 2001 and recently upgraded to Money 2004. One the issues i've had with both Money and prior versions of Quicken is the inability to accurately record the dates for money transfers from one account to another (especially from a Checking account to a Credit Card) where the posting dates are different.

If i transfer x dollars from my checking account to pay off my MasterCard... my bank statement shows the transaction occuring on 01 OCT 2003 whereas my credit card statement shows the transaction occuring on 30 SEP 2003.

I'm trying to subtract dates, to calculate time duration. I'm subtracting column A from column B into column C. Column C is formatted 'm "mos", dd "days"' and columns A and B are formatted 'mm/dd/yy/@' Unfortunately each of the durations is 1 month too long. That is, if the real duration is 4 days, column C will display '1 mos, 4 days' Any clue what I'm doing here? Thanks much.
