Hi,  i have a simple report with one static parameter.  I have no problem passing the parameter using the report viewer but I want to use the reportdocument because I simply want to write the report results to disk as a pdf.  I followed the code on page 328 listing 16-2 of Brian Bischof's book but get a missing parameter error.  I have checked that the names match and that  the collection has the values in it etc.  can anyone help?
