The error message states "An error occurred while creating features. (Duplicate field names are not allowed. ())" The file is a list of names, addresses, cities, zip codes and telephone numbers and saved as a .cvs file. I am new at this but don't find any duplicates filed names, although some last names are the same. Any thoughts?
Maybe you have a reserved field name that is used by arcmap... you might want to provide a list. Perhaps fields like ID come to mind
Thanks
Adding to Dan, also ensure the intended FieldNames shouldn't have space in them.
e.g.
Tel Nos (Incorrect)
Tel_Nos (Correct)
Thanks
