Hi, I cannot replicate Karl's problem. I copied the code examples, and got the right results on Org 8.0-pre (pulled this morning).
I did have to make one change -- Babel wouldn't recognize the variables until I passed them with :var rather than in parens after the codeblock name. (I saw there was some discussion on dropping the latter syntax; whoa -- has it already happened?) But that much was clear from the error messages I got, so Karl's problem must be something different.
