[Therion] Maps of maps at lower level in survey tree

[alastair gott]

Hi Therion Mailing list,

I'm struggling with something after a surveying trip on Saturday (I've drawn everything up) but now want to strip the survey into lower and upper sections.

At present I can run the top level .th file and stripped down config file to get the survey tree out (so I could select surveys individually at a lower level).

However when I'm trying to use the code used in the Therion samples [installed on download].
therion/samples/map-offset/thconfig.4 it doesn't work.

Please find below my error message, .th and config files, does anyone know where i'm going wrong?
