Post To A DB

Alright so here is what I am trying to do.

I have a form that someone fills out it has a text box as title, and a drop down box that is a category, and then a text area that is for their explanation.

On the back end I am using a stored procedure called sp_store_bkm. When I execute this it works just fine and puts the data that I put in it into the to table below is the  Stored procedure code:

ALTER PROCEDURE sp_store_bkm
@oID nvarchar OUTPUT,
@oTitle nvarchar(50), 
@oCategory nvarchar(50),
@obkmtext nvarchar(MAX)

 AS BEGIN
 
INSERT INTO tbl_bkms(Title, Category, bkmtext)
VALUES(@oTitle, @oCategory, @obkmtext)
Set @oID=  SCOPE_IDENTITY()
END

 

Now on my front end it comes up with an error in the lower left (erros on page). When I click on the error for details it seems like it is coming fromt he connection string. I cant find anything wrong with the connection string. Below is my code for the aspx page.

<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">


<script>

function Submit2_onclick() {

Dim Connection As SqlConnection = "server=localhost;Database=BKM.mdf;integrated security=SSPI;"
        connection.Open()
        Try
            Dim command As SqlCommand = New SqlCommand("sp_store_bkm", connection)
 
            command.CommandType = CommandType.StoredProcedure
            Dim oID As New SqlParameter("@oID", SqlDbType.Int)
            oID.Direction = ParameterDirection.Output
 
            command.Parameters.Add(oID)
            command.Parameters.Add("@oTitle", title.text)
            command.Parameters.Add("@oCategory", category.text)
            command.Parameters.Add("@obkmtext", bkmtext.text)
            command.ExecuteNonQuery()
 
            Dim sOrderID As String = oID.Value }
</script>
