\label{Spreadsheet_Referencing_Parameters}

In the assessment-level spreadsheet, the parameters are available for
calculation in three ways.

1. Reference the cell containing the parameter: \texttt{A7}

2. Reference the parameter by name: \texttt{[parameter\_0\_weight]}

In each of these two cases, the value of the parameter will replace the
reference before the Perl code in the cell is executed.

3. Use the &PARM() function, this will get run as part of the perl
   code evaluation.
