Be sure have THREE columns of data.

Trying to import X, Y data comes back with a floating point error, not 
very helpful.

If you don't have Z or attribute data for each position, just load the 
data up in a spreadsheet (if it is relatively small) and add a third 
column of zeros, and then it should work.
Wasted a couple of hours figuring that one out. help:  man s.in.ascii

e.g:
s.in.ascii input=FileName.txt sites=SitesName fs=tab

Also of note:
s.to.rast only converts each X,Y site to a raster (little dots), if you 
want an interpolated surface, use s.surf.rst.
