Hi, Here is the simplest example I could write: ---- main.org * slide 1 2. [@2] Works 3. Also #+INCLUDE: "./doesnotwork.org" ---- doesnotwork.org ** Lorem 9. [@9] \small ipsum 10. ipsum - If I try to "org-beamer-export-to-pdf" "main.org", I get: org-do-latex-and-related: Args out of range: 0, 1 - If I remove the \small on lines "9." it works. - If I copy-paste the content of "doesnotwork.org" into "main.org" it works. Is this behavior normal? - I cannot manage to find nor the problem (but I'm a n00b in org mode) nor a workaround. I would be glad if someone could help. Thanks in advance Guillaume
