get edit template control value in Gridview

[lisat76]

I have a gridview that has two edit item templates which have controls textbox and a label I want to get the value of the controls when I update the gridview and add that to the update parameters. I keep getting object reference not set to an instance of an object for the label and the textbox. I cannot figure this out.
I can't believe this has stumped me as I know I have done it before and it is very simple I must be over looking something.
here is my vb

Protected Sub GridView1_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs)
 Handles GridView1.RowUpdating
      
	  Dim varSSN  As Integer = CType(GridView1.FindControl("lblSSNed"), TextBox).Text 'GridView1.SelectedRow.Cells(1).Text
        Dim varEmpID  As Integer = CType(GridView1.FindControl("txtEmpID"), TextBox).Text
 
        sdsMissedImports.UpdateParameters.Item("SSN").DefaultValue = varSSN
        sdsMissedImports.UpdateParameters.Item("EmpID").DefaultValue = varEmpID
        sdsMissedImports.Update()

    End Sub

here is my gridview

<asp:GridView ID="GridView1" runat="server"          <Columns>
            <asp:CommandField ShowEditButton="True" />
           
                <asp:TemplateField >
                <EditItemTemplate>
               <p> Enter This employees Employee ID and Click update to 
               <br />   import all of this employees missed imports into Health/Dental Etc Databases. 
               Please Verify you have the correct EMPID before doing this</p>
                <asp:Textbox id="txtEmpID" runat="Server" />
                <asp:RequiredFieldValidator ID="reQEmpID" runat="server" ControlToValidate="txtEmpID" ErrorMessage="EmpID is Required" />

                        ValidationExpression="(\d{1,11})" Display="None"></asp:RegularExpressionValidator>
                        <ajaxToolkit:ValidatorCalloutExtender ID="EmpCallOut" runat="server"

                </EditItemTemplate>
                </asp:TemplateField>
          <asp:BoundField DataField="Name" HeaderText="Name" ReadOnly="True" SortExpression="Name" />
            <asp:TemplateField HeaderText="SSN" SortExpression="SSN">
                <EditItemTemplate>
                    <asp:Label ID="lblSSNed" runat="server" Text='<%# Eval("SSN") %>'></asp:Label>
                </EditItemTemplate>
                <ItemTemplate>
                    <asp:Label ID="lblSSN" runat="server" Text='<%# Bind("SSN") %>'></asp:Label>
                </ItemTemplate>
