Undeclared Control in ASP

[Codehammer]

Assume it Connects to the DB and here is part if the Body:

While Not rs.EOF          ' rs is the recordset
    Response.Write("<tr>")
    Response.Write("<td align='left'><i>" & rs.Fields(0).Value & "</i></td>")
    Response.Write("<td align='left'>" & rs.Fields(1).Value & "</td>")
    Response.Write("</tr>")
    CountryValueList &= "<option value = " & rs.Fields(1).Value & ">" & rs.Fields(0).Value & "</option>"
    rs.MoveNext
    End While
    response.write("</table>")
    Response.Write("<br><h4 align = 'center'><SELECT name='CarValue' id='ZarValue'>" & CountryValueList & "</SELECT>")
    DatabaseConnection.close
'If (Request.Form("btnCalculateRate") = "Calculate Rate") Then
    'button was pressed
    'Else
    'Session.Abandon
'End If
    Response.Write("<br><h4 align = 'center'>" & CarValue.selectedindex.value & ")
Response.Write("<br><input type='submit' name='btnCalculateRate' value='Calculate Rate'/>

CarValue is the name assigned to the Combobox.
CountryValueList is the name of the countries and the value for each Country is an ID for Example:
South Africa is the Item displayed, its hidden value is 0.88 for example
The problem is the line:
Response.Write("<br><h4 align = 'center'>" & CarValue.selectedindex.value & ") gives the error saying CarValue is undeclared. I also would Like the Code where if I click Sumit it would take the Current Selected Country in the ComboBox, then Display it in a Label. That is what I Am trying to do in the If Statements:

'If (Request.Form("btnCalculateRate") = "Calculate Rate") Then
    'button was pressed
    'Else
    'Session.Abandon
'End If

Thanks
