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
