All -

I need some help debugging a Null Reference Exception error I keep getting
when callling a specific method from a COM object reference.

I need help getting started where to look to see what may be causing this
error.  Other method calls to this COM object perform normally, but this
specific call returns the following error:

Sysyem.NullReferenceException: Object reference not set to an instance of an
object.

Thanks in advance for the help.
