Sorry I may not have explained this properly.
What I need is a formula to count the items selected/bought in week ending 3/8/2018 etc. In this case, this would be Mobile phone 1, laptop – 2, tv – 1 and DVD player – 1 and the same for week ending 10/8/2018.
Once I have these results I then need to know the quantity of items sold against each product in w/e 3/8/2018 and 10/8/018. I.e.
3/8/2018 - Mobile Phone (5 sold), laptop (11 sold), tv (7 sold) and dvd player (5 sold)
10/8/2018 - Mobile Phone (3 sold), laptop (9 sold), tv (15 sold) and dvd player (0 sold)
Could you help me with the formula to show the above as I then need to create a graph (clustered/stacked)
