Ben, if you can reproduce this with verbose logging enabled or give me the D:\lab3\lab3.mdb\occurrences table so I can reproduce it, I would really appreciate it. That would help me get to the bottom of it quickly.

My guess is that it is a bug in the tool. It appears to be calling Statistics_Analysis and requesting the SUM of the Shape field:

Statistics_analysis(*args=(u'TempLayer29F121B3', u'C:\\Temp\\GeoEcoTemp_bbest\\tmpbob73r\\Fishnet.mdb\\Statistics', u'Shape SUM', u'cellid')) 

Looking at the parameters you passed:

Executing (Create Fishnet for Points): ArcGISFishnetsCreateFishnetForPoints D:\lab3\lab3.mdb\occurrences D:\lab3\lab3.mdb\cells 1 1 # taxon_key # # "Lower Left" # # # # # # Continents # # CellID CellCol CellRow CellArea # 0 0 0 cellid 1000000 count # # # # # D:\lab3\lab3.mdb\occurrences

It does not appear that you requested that this be done. This suggests a bug.

I will look at this problem for MGET 0.7.

This was a bug. Fixed in [356], released in MGET 0.7a10.
