This may sound easy, and I thought it would be easy, but after som thought I
realize that what I'm trying to do probably requires a bit of hard-thinking.
I have got a table that I exported from my database (Access) and it has 3
columns (call this list1)
1. Date1
2. Date2
3. A value
Now, I have created another column with dates (in chronological order),
ranging from 2005-01-01 to 2007-10-31 (call this list2) and I want - for each
of this dates - to have a SUM of all values THAT have the date in their
interval (interval between Date1 and Date2).
So, for my first date in list2: "2005-01-01" I want to have a total sum of
all values in list1 where "2005-01-01" is between Date1 and Date2.
And so on for rest of the dates in list2 (2005-01-02 -- 2007-10-31).
(I really need this for a much promised and anticipated report analyzing our
sales, so all help is MUCH appreciated)
Cheers,
Mikael
