Request.Param not returning a value

[Nancy.]

Hello:
I have created an asp.net small app with an example from
visual studio .net.

Below is part of the code.

I am displays a select box. When selecting an item, It
should jumped to simplepage.aspx with a value rptdid.

The problem I am having is that the value is not passing
with it.
Could you please advice on what I am missing.
Thanks!

Main HTML

function jumpToPage(obj)
{ var url = obj.options[obj.selectedInd ex].value; if
(url != "none") { parent.frames
["contentfra me"].location = url; }
}

<select name="select" onchange="javas cript:jumpToPag e
(this)" class="DropDown Menu" ID="Select1">

<option value="simplepa ge.aspx?rptid=< %# "Test"%

">Report1</option>

</select>
