TURF using Python for SPSS 'list index out of range error'

[Felicity_26]

Hi there,

I am experiencing a persistant error with my Python plug in for SPSS when conducting a TURF analysis.  It keeps telling me the 'list index is out of range'.   I have absolutely zero programming or code knowledge so I am completely at a loss as to what this means and how to fix it.

Any help is greatly appreciated!

Thanks
Felicity
