[GRASS-user] v.select - so close but so far!

i'm using v.select as such:

v.select ainput=buildings atype=point alayer=1 binput=clipper btype=area
blayer=1 outpout=buildclip operator=overlap

where buildings are a point, with layer 1 (verified through QGIS)
where clipper is a polygon that is the bounds i want to pull the building
points from.  the odd thing about this dataset, is that when i go to load in
QGIS, there are two layer options, layer 0 which is polygon and layer 1
which is line.

i cant specify blayer=0 in this function or it says must be 1 or greater.

is there a way to put the polygon layer on layer 1? i can only think this
might be why there's a problem.  I still dont really grasp the layers
concept very well.  i understand it has to do with linking features to a
database, but why does it put different features on different layers?

the output i get is a file with no data in it.
