ช่วยดูโค้ให้หน่อยค่ะ พอรันแล้วมันแจ้งว่า invalid colum name 'companyMap'

protected void bt_consave_Click(object sender, ImageClickEventArgs e)
    {
        SqlConnection con = new SqlConnection(connect);
        con.Open();

        String CurrentFileName = fup_companyMap.FileName;
        String CurrentPath = Server.MapPath("~/backend/image/product/");
        if(fup_companyMap.HasFile)
        {
            CurrentPath += CurrentFileName;
            fup_companyMap.SaveAs(CurrentPath);
            Response.Write("success upload file");

        }
        else
        {
            Response.Write("don't success upload file");
        }
        System.Text.StringBuilder str = new System.Text.StringBuilder();
        str.Append("insert into contact (companyName,companyDetail,companyAddress,companytPhone,companytMail,companyMap) values (@companyName,@companyDetail,@companyAddress,@companytPhone,@companytMail,@companyMap)");
        SqlCommand com = new SqlCommand(str.ToString(), con);
        com.Parameters.AddWithValue("@companyName", tb_companyName.Text);
        com.Parameters.AddWithValue("@companyDetail", tb_companyDetail.Text);
        com.Parameters.AddWithValue("@companyAddress", tb_companyAddr.Text);
        com.Parameters.AddWithValue("@companytPhone", tb_companyPhone.Text);
        com.Parameters.AddWithValue("@companytMail", tb_companyMail.Text);
        com.Parameters.AddWithValue("@companyMap", CurrentPath);
        com.ExecuteReader(); ---> มันแจ้งว่า invalid colum name'companyMap'
        con.Dispose();
    }
