COUNT BETWEEN A SPECIFIC DATE RANGE

Hi. Our yearly calendar runs from 01/11 - 31/10 every year.

I have a spreadsheet that contains dates from 01/11/2006 onwards in column
a. I would like to be able to mark the dates that are in the year to a date
shown on another spreadsheet.

So....if the date shown is 25/04/2007, I would like to be able to mark each
row with a date between 01/11/2006 and the 25/04/2007. If the date shown is
25/04/2007, then each row with a date from 01/11/2007 to 25/04/2007 and so on.

I know this is quite complicated and have tried to think of a practical
solution but to no avail. If anyone can help it would be really appreciated.
This is an example of the formula i am using at the moment:

=IF(AND(M2=DateCell,M2=DATE(YEAR(DateCell)-1,MONTH(DateCell),DAY(DateCell))),"Yes","No")

Thanks
