Hi Urs, well, let's say bad luck... but I am still confused about having root [30] h1.Scan("mseB0","mseB0>5.2121&&mseB0<5.21213") ************************ * Row * mseB0 * ************************ * 670 * 5.2121224 * * 1962 * 5.2121224 * ************************ ==> 2 selected entries exactly the same with that level of precision...
