Re: [O] [babel] Error when exporting a trivial org file to HTML: Wrong type argument: stringp, (results . "")

[Eric Schulte]

Hi Leo,

On my system with the latest Org-mode I get the following slightly more
helpful error message.

  variable "foo" must be assigned a default value

Please add a default value to the foo variable for export and evaluation
of the code block to work.

Best -- Eric
