Transferring data from one sheet to another

[jdsg0]

Hi I would like to summarise my daily sales but cannot get the vertical data on sheet 1, to be displayed horizontally on sheet 2.

On sheet 1, you will find all the core data that will be input.
In columns N and 0 you will see the summation of the shop sales and orders by day.
The start of the week is on Monday so the first Monday of the 2017 financial year will be 10th April 2017.
All I want to do is take the vertical daily sales and orders in sheet 1 and sum them horizontally in sheet 2 - but I cannot do this by copying down so have to do it manually.
Is there a formula that can do this easily starting from 10th April and summing every week for the entire year?

Thanks in advance
