Community Championcould you not create a date table, and then assign the first or last date of the week to your week numbers? Then it would be able to rollup easily.
OK, I've added an extra column to the date table populated with the first day of that week but I don't see how this helps me.
I'm just getting frustrated now so am tempted to nuke the whole report and start from scratch (and maybe learn what I'm doing first)

id go with option 2, sometimes you just have to start from scratch.
1. create a date table
2. link that date table to your transactional data
this is definitely best practise and make sure your data types are set correctly, this gives you access to a multitude of data functions.
other dax functions you can use for the previous year values

Started with a rebuild but everything's the same :/
I can't work out how to get it to look week numbers year-to-year rather dates i.e.; week 08 in 2016/17 doesn't have the same dates as week 08 in 2015/16
PARALLELPERIOD comes close, but will only let me look at years/quarters/months
