OLE Structured Storage - Visual C++

Here's the situation:

I'm developing in VC++1.52.  
I have successfully created the following structured storage:

root storage

  "Original" - Sub Storage
                       "OriginalStream"  -  Stream
 " Archive" - Sub Storage

 " Loaded" - Sub Storage

 I can see that my storage structure  exists by using the editor in VC++ 5.0.  

PROBLEM:

When I try to open the "Original Stream" with the OpenStream  function, I get an INVALID_PARAMETER error.  
By looking at my structure is there an obvious problem with my design?  or Is there a problem with my call and if so what?
:
LastError = AsciiStorage.pIstorage->OpenStream("ORIGINALSTREAM",NULL,STGM_READWRITE | STGM_SHARE_EXCLUSIVE,0,&AsciiStream.pIStream);


Thanks

There's one thing I noticed is that the first argument to OpenStream is declared as

  const OLECHAR __RPC_FAR *pwcsname

Have you tried using L"OriginalStream"? All the other parameters look okay. What about AsciiStorage.pIstorage? Have you verified that opened okay and that it is the substorage and not the root storage?
