   In multi-part questions, the exported value for ``tries''\index{tries} is 
   the average number of tries to get the parts correct. 
   The full data for each part is still stored by the system. To assign partial credit based on number of tries, see the example in \textbf{Special Functions} (\ref{Spreadsheet_Functions}).
