Hello,
I used XIRR many times in the past but today when i tried to use it, i
couldn't. I checked the Data --AddIns and the ATP is clicked so i don't
understand why it's not working. I'm using Excel 2003 and as mentioned
before
- used XIRR many times in the past.
I also tried to check and uncheck the ATP and even restart the computer,
and
I still can't find the XIRR.... any ideas why this is happening and how I
can
fix it? HELP!!

Thanks!
