Specification link to Recipe

Hi

This is a great blog regarding recipe development but I am having issues, I can create basic specifications, however when I go and try and link this specification to a recipe, I am getting no values in the specification list. It would be very helpful if I could get a bit more understanding on the link between the specification and recipe. I may have missed something in the configuration.

I am trying to use the Fiori apps for Recipe Development.

I can see the specifications in CG02.
