The solution to {Meter==11 && Meter < 6} is the empty set, so I think > Mathematica is doing exactly what it should do. > > 3. I would avoid using a symbol called "Meter" because there's a good chance > it'll conflict with some other use of the symbol > > David I dunno. If some gal was simultaneously equal to 11 and less than 6, I might be curious to meter. Daniel Lichtblau Wolfram Research (and ducking for cover)
