        email, password = edit_user(session["username"])
        session["error_message"] = " "

        if request.method == "POST":
            name = request.form["name"]
            phone = request.form["phone"]
            message = request.form["message"]
            result = send_email(email, name, message, phone) #method to check the form data and to actually send it
            if result == "Thank you for your message. We will get back to you shortly.":
                error_message = _("Thank you for your message. We will get back to you shortly.") …
