couldnt make it work truely

<html>
<body>
{% for greeting in greetings %}
{% if greeting.author %}
<b>{{ greeting.author }}</b> wrote:
{% else %}
An anonymous person wrote:
{% endif %}
<blockquote>{{ greeting.content|escape }}</blockquote>
{% endfor %}
<input type="checkbox" name="option 1" {% if not greetings.opts or "option
1" in greetings.opts %}checked="1"{% endif %} /><span class="font90" style="
cursor:default;" >{{("Option 1")}} </span>
<input type="checkbox" name="option 2" {% if not greetings.opts or "option
2" in greetings.opts %}checked="1"{% endif %} /><span class="font90" style="
cursor:default;" >{{("Option 2")}}</span>
<p><p>

<form action="/sign" method="post">
<div><textarea name="content" rows="3" cols="60"></textarea></div>
