Hello again,

I am very slowly getting there. as a complete beginner some weeks ago I am getting a little more confident, but my internship is drawing to an end and I really need to deliver my work soon ! I have decided to simplify my power pivot needs, by appending my 2 sets of data to make the final graph work. I tested that, it works 🙂

Now all I need to do is to repeat rows in my first data-sheet, as you suggested, to have an entry for each week where I should have an impact score.
I've managed to repeat rows, thanks to various posts on your website. You'll find the results in the enclosed, much simplified file.

However, I can't see how I can increment the week numbers (WEEKSTART column).

In my file,
on page HOPEDfor, column in red, what I'm looking to do (example only given on first 2 actions).
on page SOURCE is the initial data.
on page RESULT is the current query result.

I thought an index column would help, so I could create a sort of drill down type thing, or conditional column, but I don't know how to drill down, and I don't know how to create lines with only the first date filled in.
By the way, I only did the week start and week end columns to try and get started, they can be deleted if needed. ALso, my data set should never be huge so it doesn't really matter if we need to repeat lines per day (although some actions last 9 months so that would be messier). 

Any more help would be really, really appreciated. I'm almost there !

Thanks, Eleanor
