<div class="markdown level1 remarks"><p>The expression can refer to report parameters but cannot contain references to report elements, 
fields in the data model, or aggregate functions.</p>
    <p>In the case of a parameter for a <a class="xref" href="GrapeCity.ActiveReports.PageReportModel.DataValue.html">DataValue</a> query, 
the expression can only refer to report parameters that occur earlier in the parameters list. 
The value for this query parameter is then taken from the user selection for that earlier report parameter.</p>
