dataadapter fill missing parameter
<p>I recieve the following error when I try to execute this code. But I added it to my commands. Can someone point out the step that overlooked? Thanks.</p>

<p>Procedure or function 'usps_getContactDetails' expects parameter '@aspContactID', which was not supplied.      </p>

<p>SqlConnection conn = new SqlConnection(GetConnString());
            SqlCommand cmd = new SqlCommand("usps_getContactDetails", conn);</p>

<pre><code>        SqlParameter parmContactID = new SqlParameter("@aspContactID", Convert.DBNull);
        cmd.Parameters.Add(parmContactID);
        parmContactID.Direction = ParameterDirection.Input;

        SqlDataAdapter da = new SqlDataAdapter();
        da.SelectCommand = cmd;

        conn.Open();
        DataSet cusDS = new DataSet();
        da.Fill(cusDS, "Contacts");
</code></pre>
