Hello,

I have the following information:

Ope Date Ammount Start Date End Date
09/11/2006 5.000 09/11/2006 09/11/2007

In the first year you charge 4.50%
If I need to muply the ammount with the %change IF the operation date is
between the start and the end date, haw should I write the formula?
IF(StartDate=OpeDate<=EndDate, 4.50%*Ammount,0)...this didn´t work!

Please help as soon as possible!
