Hi

This was working, have gone back to it to make a few small changes and now getting the following error whenever I click the form ....

Server Error in '/' Application.
Collection was modified; enumeration operation may not execute.

Have spent a day looking at it and cannot resolve it. Can you point me in the right direction please .... it is on a new server.

Also, is it possible to save the Thumbnails into a different directory to the images?

Thanks, John
