Hi Ivan, what type of data (integer, real, string) are HC01_VC04 or HC01_VC03 and what type od data you defined for the new column you want to create?
If the new column is real, try to use 100.0 (with decimal) instead of 100. ralf -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Re-Field-calculator-QGIS2-4-division-error-tp5157715p5157871.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
