I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind:

Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick
    'Collect Data
    Dim myDept = txtDept.Text
    Dim myFirst = txtFirstName.Text
    Dim myLast = txtLastName.Text
    Dim myPrefix = txtCoursePrefix.Text
    Dim myNum = txtCourseNum.Text

    'Define Connection
    Dim myConn As New OleDbConnection
    myConn.ConnectionString = AccessDataSource1.ConnectionString

    'Create commands
    Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn)

    'Execute the commands
    myConn.Open()
    myIns1.ExecuteNonQuery()
End Sub
