HELP!!! - Procedure Or Function SpInsertNewProduct Has Too Many Arguments Specified

Hi All,

 I'm getting this annoying message when I try to call my Sp on an insert. I've executed the SP straight from SQL Server 2005 Express and it works fine. but I think I have a problem how I'm calling it.

 The SP-------------------------------------------------------------------------

ALTER PROCEDURE dbo.spInsertNewProduct(

@productName nvarchar(50),

@productSummary text,

@productDesc text,

@productPhoto int,

@productFeaturelist text,

@productTestimonials text,

@productFile1 int,

@productFile1_Title nvarchar(50),

@productFile2 int,

@productFile1_Title nvarchar(50),

@NewProductID int OUTPUT
)AS

-- inserts new product

INSERT INTO [tbl_products] ([productName], [productSummary], [productDesc], [productPhoto], [productFeaturelist], [productTestimonials], [productFile1], [productFile1_Title], [productFile2], [productFile2_Title])

VALUES (@productName, @productSummary, @productDesc, @productPhoto, @productFeaturelist, @productTestimonials, @productFile1, @productFile1_Title, @productFile2, @productFile2_Title);

-- Read the just-inserted productID into @NewProductID

SET @NewProductID = SCOPE_IDENTITY();

-------------------------------------------------------------------------

The DataSource-------------------------------------------------------------------------

<asp:SqlDataSource ID="dsproduct" runat="server" ConnectionString="<%$ ConnectionStrings:myConn %>"
            InsertCommand="spInsertNewProduct" InsertCommandType="StoredProcedure">
            <InsertParameters>
                <asp:Parameter Name="productName" Type="String" />
                <asp:Parameter Name="productSummary" Type="String" />
                <asp:Parameter Name="productDesc" Type="String" />
                <asp:Parameter Name="productPhoto" Type="String" />
                <asp:Parameter Name="productFeaturelist" Type="String" />
                <asp:Parameter Name="productTestimonials" Type="String" />
                <asp:Parameter Name="productFile1" Type="String" />
                <asp:Parameter Name="productFile1_Title" Type="String" />
                <asp:Parameter Name="productFile2" Type="String" />
                <asp:Parameter Name="productFile2_Title" Type="String" />
                <asp:Parameter Direction="Output" Name="NewProductID" Type="Int32" />
            </InsertParameters>
        </asp:SqlDataSource>
-------------------------------------------------------------------------

 In code behind I grab params from front end dropdowns:
-------------------------------------------------------------------------

    Sub InsertProduct(ByVal Src As Object, ByVal Args As DetailsViewInsertEventArgs)


        dsProduct.InsertParameters("productPhoto").DefaultValue = CType(dvEditProduct.FindControl("ddlProdImage"), DropDownList).SelectedValue

        dsProduct.InsertParameters("productFile1").DefaultValue = CType(dvEditProduct.FindControl("ddlProdFile1"), DropDownList).SelectedValue

        dsProduct.InsertParameters("productFile2").DefaultValue = CType(dvEditProduct.FindControl("ddlProdFile2"), DropDownList).SelectedValue

        lblStatus.Text = "Product has been added to the database"
    End Sub
-------------------------------------------------------------------------

I can't see how in the VB front end file how there can be too many params? Any help is greatly appreciated!
