Hi Charles, I think I found precisely the issue I'm having.
When I use your example, and adjust it slightly: #+NAME: block-1 #+BEGIN_SRC shell :var x="X" echo ">>>" $x "<<<" #+END_SRC #+BEGIN_SRC shell :var c="test" y=block-1(c) echo $y #+END_SRC #+RESULTS: : >>> $c <<< I added a reference to an argument defined within the same block. I get the aforementioned error: org-babel-ref-resolve: Reference ācā not found in this buffer Thanks! Zack
