  Modified files:              
    /loncom/interface/spreadsheet	Spreadsheet.pm 
  Log:
  Modification to &expandsum:  If we cannot locate the parameter, return '""'
  instead of a string describing the parameter we could not find.  This
  keeps a lack of a parameter from blowing up a cell computation.
