I have an odd problem I have been trying to troubleshoot for some time. On one of my many DNN sites I use the Reports module to display data as results from motor racing events, the data is input into the DB via a form.

I now have an issue on one of the sites where I want to copy a page that has all the Reports modules listed for each racing class with the query, I want tot copy all the modules to get the query language, so I have to do is update one string in the query to display the desried results. This has been working for quite some time.

Now when I attempt to do this copy, I get an error - Object reference not set to an instance of an object.

This only happens when I want to copy the modules, if I set them to New it works, but of course I do not get the queries to copy within the modules.  When I do get the error, it creates the page and the the first module, but bombs out when it tries to copy the query from the module.

Any help on why this might be happening and how I might fix it would be greatly appreciates, this is causing me a lot more time to update the site.  I do not think it is the Reports Module, I think it is something else causing the problem.

Here is the full error:
