There are many ways. For example like Micha said:
--%<--
I'm including a mapset "bombay" with the contour vecto, the contour 
raster and the resulting dem.
Like Achim said, first you must convert the HEIGHT column to integer (I 
did this with Openoffice Calc).
--%<--
here he means the dbf-file

or you change the table after imported
(using SQL)

check your projection units (g.proj -p)
and your region (g.region -p)
