I'm trying to setup an Amount of Progress graph in Discover and failing miserably. Can anyone offer any advice or screen shots of how they have got this set up?

At the moment in SIMS: Discover Aspect Detail I have the the mode of Amount of Progress looking at the B Maths Level for both the from and To Source Aspects and then the results sets of the last level entered last year to the latest one added this year and I'm just getting 0 displaying in Discover.

I've run the generate Discover in setup and have done a transfer Discover Assessment.
