I'm seeing a lot of errors lately while reviewing... please keep the field helps open!
There have been a lot of errors regarding the residence field: I'm seeing cards where the arrondissement number is clearly there, but nothing has been entered. Also, please do not try to decipher the street address. The only entry needed in residence field is the name of the commune, or the arrondissement number (only 1 through 20) followed by the word Paris. If either of these two things are not there, just leave the field empty... no need to mark it 'blank'.
Regarding the department field: all of the departments are in the drop down menu. Sometimes they are abbreviated - if so, please key as seen. The only exceptions to the departments in the drop down menu are the old departments of Charente Inferieure, Seine Inferieure and Loire Inferieure. These are usually abbreviated to Chte Inf, S Inf and L Inf. Sometimes you will have to key another country in the department field. Algerie, Russie and Belgique are the most common ones I have come across.
Lastly - there is no need to F7 every field - only first and last name if it stays pink after you have made your entry.
