"Workbook.SaveA s" Failing

[OutdoorGuy]

Greetings,

I have the code below where I am instantiating Excel and then attempting
to the save the new workbook (as "Test.xls") . However, on the line of
code that attempts to save the workbook, I receive the following error
message:

"Object reference not set to an instance of an object."

Any ideas as to what I am doing wrong? [Note: oWB.Save() works fine,
just not oWB.SaveAs()].

Thanks in advance!
