All I'm trying to do is get a total value for the Shape.STLength() field for a feature class. I've selected the records I care about, but when I right click on the field and choose statistics, I get the statistics for all records. The attribute table is only showing selected records, and the only filter option is by extent.
What am I missing here? This should be very simple (and it is in ArcMap, which I am seriously wishing I could just use forever).
