 \textbf{How to deal with multi-part problems}
 
 Often, there are several parts in a specific problem. For example, a
-problem with three parts would have parts 0, 11, 12, and 13. For a
-general spreadsheet, it is not often desirable to sum up all of these
+problem with three parts may have parts 0, 11, 12, and 13, where
+part 0, is the part ID reserved for the problem as a whole.  For a
+general spreadsheet, it is often desirable to sum up all of these
 parts, while not knowing how many parts there are as the spreadsheet
 is written.
 
 The spreadsheet has a preprocessor which can expand a symbolic
-expression over all symbolic names that fit. The general syntax is
+expression over all symbolic names that match. The general syntax is
 \index{EXPANDSUM} \texttt{[\&EXPANDSUM(VARNAME;expression)]}.

+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}).
