Hi Stuart

Thanks for using Sage City.

Do you have the document open in excel as if this is open Sage cant read the information, Other reasons this happens  is that there is a blank line in line 1, The mappings are incorrect or on the step choosing your file the wrong sheet may be chosen or the first line contains headings is chosen.
