{% if {{result}} == 'Invalid' %}
 <span class="error-message-uname">Invalid .</span>
{% endif %}

That depends on what version of Django you're using. Since Django 1.2, this is valid:

{% if result == 'Invalid' %}
    <span class="error-message-uname">Invalid .</span>
{% endif %}

For earlier versions, use ifequal:

{% ifequal result 'Invalid' %}
    <span class="error-message-uname">Invalid .</span>
{% endifequal %}

{% if result == 'Invalid' %}
    <span class="error-message-uname">Invalid .</span>
{% endif %}
