[GRASSLIST:1471] Using v.in.shape

[Gaetan GUYODO]

I have the following files in the same directory :
a.dbf
a.sbn
a.sbx
a.shp
a.shx
and I want to import these files (vector shapefiles)
I use in grass 5b10, the v.in.shape window in tcltkgrass
I give the good file (a.shp), OK
What is the debugging level ? I let it empty
I give a log file, OK
What is "Snap distance for node during import" ? I let it empty 
Colinearity distance, default
Init scale for vector map, default
Name of field with category attribute number : nothing
Name of field with category label : nothing
List fields in database : on

then I have the following fields :
AREA
PERIMETER
NAME
NAME_ID
DEPARTEMEN
COMMUNE2
DEPARTEMEN
COMMUNE

I think the "field with category attribute number" is NAME_ID (how can I be sure
?)
and I think the 2 names "DEPARTEMEN" are not complete (is it possible to have 2
fields with the same name ? I don't think so), how to know their complete name ?
In the window, I want to give a few "names of fields with category label", but
what delimiter doI use (: ; , . or an other one, or impossible)

When I try whith these informations, I had these messages :

Not assigning category labels
WARNING: No attribute value field assigned. Using record ID.

What do I do to have not a PNT_TO_AREA failed (what's that) ?
If you can help me, that will be very good...
thanks
