How do you set an "If" option on an entry that includes "contains"

Question

I am trying to set an if statment that will show a li if there is only one entry displaying. The issue I am having is that this entry is put into two different places via checking if it contains a checkbox. I can only seem to managed to get it to display all the time or not at all

The code I have at the moment is this {% if entry.ENTRYNAME.contains('CHECKBOX OPTION') == 0 %} <li>CONTENT</li> {% endif %}

But that does not seem to work. I am using the Check box contains option else where and it works fine. It's just the value check that I cannot seem to get to work. I've also tried adding both .length and |length but neither of those seem to work.

OKay so the solution I found is this. It was much more complicated than I wanted it to be but it works.

{% set VARIABLE = 0 %}
{% for entry in craft.entries.section('ENTRY') %}
    {% if entry.FIELDNAME.contains('CHECKBOX OPTION') %}
        {% set VARIABLE = VARIABLE + 1 %}
        <li>CONTENT</li>
    {% endif %}
{% endfor %}
{% if VARIABLE <= 1 %}
    <li>CONTENT</li>
{% endif %}

I'm not entirely sure what you're trying to do, so I don't know if these suggestions will help at all.

If you want to check if a checkbox field only has one option checked then you can simply use

{% if entry.FIELDNAME|length == 1 %}
    ...
{% endif %}

If you're trying to show it in one location if a certain checkbox is checked, and a different location if a different checkbox is checked, then try...

{# location one (maybe header) #}
{% if entry.FIELDNAME.contains("Use Location 1") %}
    <li>CONTENT</li>
{% endif %}

{# elsewhere, location two (maybe footer) #}
{% if entry.FIELDNAME.contains("Use Location 2") %}
    <li>CONTENT</li>
{% endif %}
