Hi Sean, I uploaded the shapefile together with a demo script here: http://flatpolar.org/floatval.zip
Executing the script produces the following output with my setup: Item Nr. 0 : 1.0 Item Nr. 1 : 613.0 Item Nr. 2 : 1.0 Item Nr. 3 : 0.0 Item Nr. 4 : 1.0 Item Nr. 5 : 1.0 Item Nr. 6 : 0.0 Item Nr. 7 : 1.0 Item Nr. 8 : 1.0 Item Nr. 9 : 500.0 while the output should be: Item Nr. 0 : 1.5 Item Nr. 1 : 613.0 Item Nr. 2 : 1.5 Item Nr. 3 : 0.94 ... The attribute field used is named 'LEISTUNG'. I'm probably just doing something wrong here, but I'm really stuck. Thank you very much for your support, this is highly appreciated! Best regards (and since this is my first post here, hello to everybody). Michael > Hi Michael, > > I can't reproduce this error with any data I have.
