How to get fields from another section? I need to get data from fields from another section. 
My code is:

        {% for kontaktEntry in craft.entries.section('kontakt').entry.kontakter %}
            &lt;div&gt;
                &lt;a href="{{ kontaktEntry.epost }}"&gt;
                    {% set image = kontaktEntry.bilde.first() %}
                    {% if image %}
                        &lt;img src="{{ image.getUrl() }}" width="100" height="100" alt="{{kontaktEntry.navn}}"/&gt;
                    {% endif %}
                    &lt;h3 class="center"&gt;{{ kontaktEntry.navn }}&lt;/h3&gt;
                    {{ kontaktEntry.stilling }}
                &lt;/a&gt;
            &lt;/div&gt;
        {% endfor %}


kontakter is a matrix. I get nothing in output. What is wrong here?
I'm not sure that .entry is a valid parameter? I think that craft.entries.section('kontakt') contains an array with entries, so maybe you you could do .first on it, so basically I think you wanted to do this:

    {% for kontaktEntry in craft.entries.section('kontakt').first.kontakter %}
        &lt;div&gt;
            &lt;a href="{{ kontaktEntry.epost }}"&gt;
                {% set image = kontaktEntry.bilde.first() %}
                {% if image %}
                    &lt;img src="{{ image.getUrl() }}" width="100" height="100" alt="{{kontaktEntry.navn}}"/&gt;
                {% endif %}
                &lt;h3 class="center"&gt;{{ kontaktEntry.navn }}&lt;/h3&gt;
                {{ kontaktEntry.stilling }}
            &lt;/a&gt;
        &lt;/div&gt;
    {% endfor %}
