Flask iteration - if not working?

So I am trying to iterate through my csv file, then retrieving data that has a 1 in one of the fields and display it. However when I run it it is saying it is expecting and endif (which I have) what am I doing wrong?

Heres the code.

{% for validated in bookingList %}
  <tr>
    {% if (value == '1') %}
      <td></td>
        <table>
        {% for aDate in bookingList %}
          <tr>      
            {% for item in aDate%}
              <td>
                {{item}}
              </td>
            {% endfor %}        
          </tr>
        {% endfor %}
        </table> 
    {% endif %}
</tr>
{% endfor %}
