Form does not submit - Symfony2 - php

Question

why does my symfony2 Form not submit?
If i press the submit-button, nothing happens.
I want not the default-form {{ form(form) }}.
The default form works.
The error seems to be in TWIG?
{% extends '::base.html.twig' %}
{% block stylesheets %}
{{ parent() }}
<link href="{{ asset('css/essensplan/show.css') }}" rel="stylesheet" />
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<!-- Optional theme -->

{% endblock %}
{% block body -%}
{{ form_start(form) }}
<h1>Speiseplan für KW {{ kw }}</h1>
<form action = "" method = "post">
<input type="submit" name="back" value="<" class="btn-lg btn-success"/>
<input type="submit" name="next" value=">" class="btn-lg btn-success" />

Thanks for your help.

It seems that you have nested forms in your markup (first one coming from twig's {{ form }} second is in markup. According to this or this you are not allowed to nest form tags. This might be the reason your form is not submitting properly
