Hi people,
I installed this tool which allows me to quickly select our meters by
transformer and it was working before. Now i cant' select the
attribute (tansformer) from the attribute drop down menu. Does anyone
know what i need to do first?.
My meter table is open straight from my PostGIS database.
Thanks,
Nome
