Wondering if somebody can help me with some errors generated by the LaHarz model.  I am trying to run the Laharz Distal Zones standalone python tool.  It was created by a USGS developer and it is supposed to work with ArcGIS 10.X.  There are four required inputs: 1) filled DEM, 2) text file of volumes (integers), separated by commas 3) a text file of XY coordinates and 4) a string denoting a prefix for output grids.  Below is the message in Geoprocessing Results.  The full python script will be attached.
