[GRASS-user] problems with v.edit

Hi all.
I have a problem with v-edit.
I have to break a vector line
into two parts near a point. I gave this command:

v.edit map=ret_125
layer=1 type=line tool=break thresh=$ris_edit coords=$x,$y snap=no

where " $ris_edit " depends on the resolution of the DEM raster map,
"$x" and "$y" are the coordinates of the point.
I'm using GRASS 6.3.

What I'm missing?

are you sure that threshold value is enough to select vector feature
which you want to break?

v.edit map=ret_125 tool=select thresh=$ris_edit coords=$x,$y

?
