You need to define a ReportParameter in your RDLC before using it:

<ReportParameters>
    <ReportParameter Name="ReportTitle">
        <DataType>String</DataType>
        <Prompt>ReportTitle</Prompt>
    </ReportParameter>
</ReportParameters>

In Visual Studio you can also use View > Report Data instead of directly modifying the RDLC.
