Hi @ramji013, if you're having a specific issue the best way to troubleshoot is to post a minimal runnable example that shows the problem you're having, possibly as a gist or issue on github. def'd variables should be visible from within rules; we do it frequently. If you're doing something in ClojureScript I'm less sure, since I haven't used that in earnest.

As for getting to nested fields, you can use Clojure's destructuring to get to the top-level field (or fact itself), and then access nested fields just using Clojure expressions as part of the rule left-hand side. Some details on restructuring are here: http://www.clara-rules.org/docs/expressions/

An announcement: Clara 0.12.0 has been released! There have been a bunch of performance enhancements from @wparker and @mikerod, and a handful of bug fixes as well. Details are in the change log: https://github.com/rbrush/clara-rules/blob/master/CHANGELOG.md#0120
