Where to insert this code?

I have a multiview inside a form view. The multiview active index is based on a dropdownlist selection, I found out that I need to put this line somewhere:
vb Syntax (Toggle Plain Text) 
  1. <script runat="server">
  2. Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) 
  3. MultiView2.ActiveViewIndex = DropDownList1.SelectedValue
  4. End Sub
  5. </script>

My page has a masterpage, so the main page looks like this:

vb Syntax (Toggle Plain Text) 
  1. <%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="test.aspx.vb" Inherits="test" title="test" %>
  2.  
  3. <asp:Content ID="Content1" ContentPlaceHolderID="mainContent" Runat="Server">
  4.  
  5. <asp:FormView ID="FormView1" runat="server" DataSourceID="sdsDetail" DefaultMode="Edit">
  6.  
  7. <EditItemTemplate>
  8.  
  9. <asp:DropDownList ID="DropDownList1" runat="server" SelectedValue='<%# Bind("Active") %>' AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
  10.  
  11. <asp:ListItem Value=""></asp:ListItem>
  12.  
  13. <asp:ListItem Value="A">Active Employee </asp:ListItem>
  14.  
  15. <asp:ListItem Value="R">Retired</asp:ListItem>
  16.  
  17. </asp:DropDownList>
  18.  
  19. <asp:MultiView ID="MultiView2" runat="server">
  20.                     <asp:View ID="View1" runat="server">
  21.                         <asp:ListBox ID="ListBox1" runat="server" DataSourceID="odsDept" DataTextField="Dept_name"
  22.                             DataValueField="Dept_name" SelectedValue='<%# bind("Dept") %>' Width="232px">
  23.                         </asp:ListBox><asp:ObjectDataSource ID="odsDept" runat="server" OldValuesParameterFormatString="original_{0}"
  24.                             SelectMethod="GetDept" TypeName="TableAdapters.A_TableAdapter"></asp:ObjectDataSource>
  25.                     </asp:View>
  26.                     <asp:View ID="View2" runat="server">
  27.                         <asp:ListBox ID="ListBox2" runat="server" DataSourceID="odsB" DataTextField="Group_Name"
  28.                             DataValueField="Group_Name" SelectedValue='<%# bind("Dept") %>' Width="232px">
  29.                         </asp:ListBox><asp:ObjectDataSource ID="odsB" runat="server" OldValuesParameterFormatString="original_{0}"
  30.                             SelectMethod="GetGroup" TypeName="TableAdapters.B_TableAdapter"></asp:ObjectDataSource>
  31.                     </asp:View>
  32.                 </asp:MultiView>
  33. </EditItemTemplate>
  34. </asp:FormView>
  35. </asp:Content>

I have had people suggesting me to put it in the vb file like this:
ASP.NET Syntax (Toggle Plain Text) 
  1. Partial Class list_pages_Details
  2.     Inherits System.Web.UI.Page
  3.  
  4.     'Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
  5.     '    dim MultiView mv
  6.     '    dim DropDownList ddl
  7.  
  8.     '    mv = (MultiView)FormView1.FindControl("MultiView2")
  9.     '    ddl = (DropDownList)FormView1.FindControl("DropDownList1")
  10.  
  11.     '    mv.ActiveViewIndex = ddl.SelectedValue
  12.     'End Sub
  13.  
  14.     Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
  15.  
  16.     End Sub
  17. End Class
  18.  

I tried putting the sub inside FormView, inside Edit Template, inside master file....
Anywhere I put it, same error:
name mv not declared....

Please help me, where can I put it, or how can I achieve what I need to do?

Thank you for your time!!!
