Hi Emma,
It seems the directions for this are wrong. Instead of using a number for the item in your menu, use the actual item name, such as: 19 Lichfield Street Surgery, Admin, or All Saints Surgery. You will also need to be careful with the settings during the actual upload. For the Existing user details you will probably have to use Override with file or Override with file and defaults.
Fill in missing from file and defaults doesn't seem to work as those fields aren't actually there yet, I think. At least it didn't for me. I checked this in Moodle 2.5 and Moodle 2.7 and they both work this way.
HTH,
AL
