Compiler Error Message: CS1001: Identifier expected C#

The following is my Dropdownlist that on SelectedIndexChanged() calls a javascrip function:

<asp:DropDownList id="DDYearRange" runat="server" OnSelectedIndexChanged="SetYearRange()";>
          <asp:ListItem Value="2004-2008">2004 - 2008</asp:ListItem>
          <asp:ListItem Value="2007-2008">2007 - 2008</asp:ListItem>

the following is my javascript function:

      function SetYearRange()
        var Yearlst = document.getElementById("DDYearRange");
        var txtHidden = document.getElementById("ReportHIddenText");
        txtHidden.value = Yearlst.options[DDYearRange.selectedIndex].text;
        return true;
I aslo have the following tag on the form:
<input type="hidden" name="ReportHiddenID" id="ReportHIddenText">

When I try to view in browser, I get the following error message:
Compiler Error Message: CS1001: Identifier expected C#

Any idea?

You can't reference DDYearRange directly in JavaScript, you need to use the 'Yearlst' reference that you got in the line before.
