Paul,

I hate to say - I wrote this a long time ago and have touched for some time. This error seems to be a common developer error when I searched on it.

Jason, I came across your column while researching the difference between files in list items and files in libraries. Although this post does not address that, might I hear a word or two on the subject?

We have lists that contain n number of file attachments, and we want to copy a selected attachment into an existing library.

Thanks!

Yeah and it took me three times over a two year period to get it absolutely correct. Doh!
