[GRASSLIST:2839] gstat: value not allowed for: data v field not found in sites list

Im trying to make geostatistics with gstat/GRASS. There are some examples in the GRASS book from Mitasova and Neteler.
I´m using the Maas UTM Location like in the example, but I always get back the same error:

GRASS site list werte: 0 cat, 2 dim, 0 str, 1 dbl.
Warning: gstat/grass doubles in site list are ignored, check data v field!
*gstat: value not allowed for: data v field not found in sites list
*
I´m using GRASS 5.0.r binaries and gstat version 2.4.3 with libraries: gd (png) grass ncurses

What can I do to get a result.

Thanks
michaela

Michaela,

your gstat installation seems to be configured well. So you have to
check two things:

- the sites data file:
   When using GRASS sites lists as input maps, following column
   order conventions have to be followed:
       Easting|Northing|#site_no %FP_data [%FP_data]
  
   To check it, run:
   s.info your_sites_file

   -> does it report 2 dimentions, 1 category, 1 or more DOUBLE
      attributes? It should (or the sites file is not right)

   The error message indicates, that the 4th column of your
   sites file is not right or contains errors.

- the gstat control file:
   Should contain something like this
     data(zinc): 'Zn', x=1, y=2, v=1;

   v1 points to the first DOUBLE attributes column in the sites file.

Please report some details.
