Masterpage insert record problem

[Bo]

Can anyone explain why the code below inserts blank values into my access
database while the same code without the masterpagefile reference works and
inserts the values?

<%@ Page Language="VB" MasterPageFile= "~/MasterPage.mast er" Title="Untitled
Page" %>

<Script runat="server">

Private Sub Insertimg(ByVal Source As Object, ByVal e As EventArgs)

SqlDataSource1. Insert()

End Sub

</Script>


<asp:Content ID="Content1" ContentPlaceHol derID="ContentP laceHolder1"
Runat="Server">

<asp:SqlDataSou rce ID="SqlDataSour ce1" runat="server" ConnectionStrin g="<%$
ConnectionStrin gs:minConnectio nString %>"

ProviderName="< %$ ConnectionStrin gs:minConnectio nString.Provide rName %>"

InsertCommand=" INSERT INTO iconimg (Imgname, Imgpath) VALUES (@Imgn,@Imgp)">

<insertparamete rs>

<asp:FormParame ter FormField="Imgn ame" Name="Imgn" />

<asp:FormParame ter FormField="Imgp ath" Name="Imgp" />

</insertparameter s>

</asp:SqlDataSour ce>

Billednavn: <asp:TextBox ID="Imgname" runat="server"> </asp:TextBox>

Billedsti: <asp:TextBox ID="Imgpath" runat="server"> </asp:TextBox>

<asp:button

id="Button2"

runat="server"

text="Insert"

onclick="Insert img" />

</asp:Content>
