Can anyone explain this error?  Thanks

The file or folder name "https://xxx.sharepoint.com/sites/training/MikeTest/_layouts/15/addanapp.aspx?Source=https://xxx.sharepoint.com/sites/training/MikeTest/AutoNumForms/ANForm - 2.xml" contains invalid characters.

Please use a different name. Common invalid characters include the following: # % * : < > ? / |
 

When you created the submit connection to SharePoint, did you just use the URL to the library? https://xxx.sharepoint.com/sites/training/MikeTest/AutoNumForms ?

Thanks Hilary,  when I originally setup the submit connection I only had the simple Url in there: https://xxx.sharepoint.com/sites/training/MikeTest/AutoNumForms/ 

After publishing it I saw that this was coming out in the error (as you see): https://xxx.sharepoint.com/sites/training/MikeTest/_layouts/15/addanapp.aspx?Source=https://xxx.sharepoint.com/sites/training/MikeTest/AutoNumForms/ 

I am not even sure what it is...but after reading your post, I rechecked it and sure enough this entire double url (or whatever it is) was being used in the connection.  So I changed it back and it seems to work now.

Thanks for pointing that out.   Do you know what the _layouts/15/addanapp.aspx even is?

Thanks very much 

I don't - & how weird that IP changed this while publishing!
