Hi Dan,
      When the IDV read in a grib format dataset, it requires a correct table. 
Sometime, if the dataset is constructed under a customized table (not available 
in the IDV), we did see this kind of exception. Not very sure if this is the 
situation here, can you provide us more information about the dataset you are 
working on.
