watche87&nbsp;, if your first formula is in first row, when
=SUM(INDEX(A:A,1+(ROW()-ROW($A$1))*7):INDEX(A:A,7+(ROW()-ROW($A$1))*7))
and drag in down. Sample is in attached file.

Thanks so much Sergei but i still cant make it work. So if i am putting the information onto a new sheet from a sheet called Daily2018 and block of 7 rows i want to copy would be D4:D10 what would the formula be then?

watche87&nbsp;, sorry, perhaps I misunderstood you. You'd like to copy information from one sheet to another by blocks of 7 rows; or you would like to make the calculations on the blocks of 7 rows? If you could provide small sample file that helps.

SergeiBaklan&nbsp;So i want to copy the weekly DRINK total figure over to my new sheet to create a week on week graph of 2018 v 2019.&nbsp;Please see example attached.&nbsp;Thanks

watche87&nbsp;, with above formula that will be
=SUM(INDEX(Daily2018!D:D,2+(ROW()-ROW($B$3))*7):INDEX(Daily2018!D:D,8+(ROW()-ROW($B$3))*7))
As variant that could be
=IFNA(SUM(OFFSET(Daily2018!$D$1,MATCH(A3,Daily2018!A:A,0)-1,,7)),0)
if only each your week has exactly 7 days. It could be SUMIFS or SUMPRODUCT if reorganize your data a bit and have week number in each row.
