Potential Set Analysis Help

[NemoAndStitch22]

Hiya, 

I'm trying to create a table in Qliksense and want it to look something like this:

Currently I've managed to get this.. 

I'm just wondering if anyone knows how to add the Year on year difference.. This needs to change when the filter changes the selection.. I think I need to use set analysis but I can't work out how to make it happen.

Any help would be greatly appreciated.

Many Thanks,

Megan
