I tried copy and past with the code Kovid supplied but again got this message
calibre, version 0.8.11
ERROR: Ongeldige invoer: <p>Kan recept niet aanmaken. Fout:<br>invalid syntax (recipe4.py, line 11)
I'm just a user, not a specialist, so I don't know what this means and how I could solve this. I do have a pass and access code for IHT online.
