Pass variable comes from a subreport to subreport2

[marcio_fe_s]

I do a report that has two subreports. The first one, just calculate some value, in a variable. When I return this value to parent report I can print this on report normally. But I need pass this same value to another subreport, but the value always is null.

I am not sure, but I think you can define a subreport parameter and set the expression of the parameter to the value of the variable previously returned.

<subreport  isUsingCache="false">
   <reportElement
      x="0"
      y="91"
      width="274"
      height="5"
      key="zerovalues"/>
      <subreportParameter  name="NameOfParameterPassedToSubReport">
         <subreportParameterExpression><![CDATA[$V{MasterReportVariable}]]></subreportParameterExpression>
      </subreportParameter>
      <subreportExpression  class="java.lang.String"><![CDATA["SubReportName.jasper"]]></subreportExpression>
</subreport>

hello Edward.

Thanks for your reply. I tried these way, but still i am getting null . The variable displayed correctly when I displayed it on the master report (returned variable), but its null when i pass this value to another subreport
