my code is : Hello!~~~

{% if user %}
    <p>Logged in as {{ user.first_name }} {{ user.last_name }}.</p>
{% elif openid_user%}
    <p>Hello, {{openid_user.nickname}}! Do you want to <a href="{{openid_logout_url}}">Log out?</p>
{% else %}
    <p><a href="/login?redirect={{ current_url }}">google Log in</a>.</p>
    <p><a href="/twitter">twitter Log in</a>.</p>
    <p><a href="/facebook">facebook Log in</a>.</p>
    <p><a href="{{openid_login_url}}">openid Log in</a>.</p>
    <iframe src="/_openid/login?continue=/"></iframe>
{% endif %}

the error is :

TemplateSyntaxError: Invalid block tag: 'elif'

does not webapp has a 'else if ' ?

thanks
