"start and end node should have the same grand parent" exception on MailMerge.Execute

Hi,
I’m having an exception with the attached Word template.
The problem occurs with this code:

document.AsposeDocument.MailMerge.Execute(ds.Tables[0])

Exception message : “start and end node should have the same grand parent”.
I don’t have any trouble with my other templates.
Would you look at this template and let me know if there’s anything I can do?

Thanks !

Hi
Thanks for your request. The problem occurs because there is section break inside field code. Just remove this break and no errors will occur. (Press Alt+F9 to see field code, on the second page after “Article5” you will see section break).
Also note that Aspose.Words does not evaluate IF field. See FAQ for more information:
Best regards.

Thanks for your help !
