Default Insert statement?

Hi

Does anyone have any experience of SQL Insert Statement. I have the below statement in one of my ASP projects. The first time the user executes the statement it works as intended and creates one entry into the corresponding table, but if the same user attempts to insert another new record into the same table again it duplicates the insert entry and you end up with three entries all in all in that table for the specific user and so on? i.e.

ATTEMPT ONE

Record 1

ATTEMPT TWO

Record 2

Record 2 COPY

ATTEMPT THREE

Record 3

Record 3 COPY

Record 3 COPY

Code:
Dim connection As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("LiteratureCataloguingConnectionString").ConnectionString)
        Dim sql As String = "INSERT INTO Loan (PublicationID, UserId, StartLoanDate, EndLoanDate, ThirdDayNotification, FifthDayNotification, FifteenthDayNotification, ThirtiethDayNotification) VALUES (@PublicationID, @UserId, @StartLoanDate, @EndLoanDate, @ThirdDayNotification, @FifthDayNotification, @FifteenthDayNotification, @ThirtiethDayNotification)"

        Dim command As SqlCommand = New SqlCommand(sql, connection)
        command.Parameters.AddWithValue("@PublicationID", PublicationID)
        command.Parameters.AddWithValue("@UserId", UserId)
        command.Parameters.AddWithValue("@StartLoanDate", SDate)
        command.Parameters.AddWithValue("@EndLoanDate", FDate)
        command.Parameters.AddWithValue("@ThirdDayNotification", (0))
        command.Parameters.AddWithValue("@FifthDayNotification", (0))
        command.Parameters.AddWithValue("@FifteenthDayNotification", (0))
        command.Parameters.AddWithValue("@ThirtiethDayNotification", (0))

        command.Connection.Open()
        command.ExecuteNonQuery()
        command.Connection.Close()

Hi there,

Is this all the relevant code? I see no reason why this code would insert multiple records, so the problem is likely elsewhere...

Cheers,

Imar
