javascript and session variable

hello all,
I have a website made ¿¿with visual studio 2010. I use a javascript function to activate a menu option, I want to activating the javascript in function of a session variable.

in the default.aspx.vb load event
Dim strQueryOutlet As String = Request.QueryString.Get("O") 'Si el valor es 1 es Outlet, si es O es promocion.
If strQueryOutlet Is Nothing Then
blnEsOutlet = True
ElseIf strQueryOutlet = "1" Then
blnEsOutlet = True
ElseIf strQueryOutlet = "0" Then
blnEsOutlet = False
Else
blnEsOutlet = True
End If

If blnEsOutlet Then
Session("EsOutlet") = "1"
Session("MenuOption") = "one"
Else
Session("EsOutlet") = "0"
Session("MenuOption") = "two"
End If

In the default.aspx
<script type="text/javascript">
if (<%=Session("MenuOption")%> = "one") {
document.getElementById('uno').className = "activo";
}
if (<%=Session("MenuOption")%> = "two") {
document.getElementById('dos').className = "activo";
}
</script>

when I run the proyect...the default.aspx dynamic show... and the two if are executed...

and the two menu option are selected, and this is a mistake...

<script type="text/javascript">
if (one = "one") {
document.getElementById('uno').className = "activo";
}
if (one = "two") {
document.getElementById('dos').className = "activo";
}

<script type="text/javascript">

document.getElementById('uno').className = "activo";
}
if ("<%=Session("MenuOption")%>" == "two") {
document.getElementById('dos').className = "activo";
}
