node_data_field not working on 6 I have this structure:

&lt;div class="FloatLeft RightText"&gt;: '.$data-&gt;node_data_field_story_text_html_field_kampanya_adi_value.'&lt;/div&gt;
    &lt;div class="clear"&gt;&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="InfoTextItems"&gt;
    &lt;div class="FloatLeft LeftText"&gt;Ajans&lt;/div&gt;
    &lt;div class="FloatLeft RightText"&gt;: '.$data-&gt;node_data_field_story_text_html_field_ajans_value.'&lt;/div&gt;
    &lt;div class="clear"&gt;&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="InfoTextItems"&gt;
    &lt;div class="FloatLeft LeftText"&gt;Reklamveren&lt;/div&gt;
    &lt;div class="FloatLeft RightText"&gt;: '.$data-&gt;node_data_field_story_text_html_field_reklamveren_value.'&lt;/div&gt;
    &lt;div class="clear"&gt;&lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="InfoTextItems"&gt;
    &lt;div class="FloatLeft LeftText"&gt;Ödül&lt;/div&gt;
    &lt;div class="FloatLeft RightText"&gt;: '.$data-&gt;node_data_field_story_text_html_field_odul_value.'&lt;/div&gt;


It's working.
And 4 other field:

field_one
field_two
field_three
field_four


When I change this field to other, not working. Like this:

&lt;div class="FloatLeft RightText"&gt;: '.$data-&gt;node_data_field_story_text_html_field_one_value.'&lt;/div&gt;


And not working on my page.

How can I fix it?
I imagine $data->node_data_field_story_text_html_field_one_value is not being set.

Try running dpm($data) if you have the devel module enabled which will show you all the object members set.

Also you should check your php error logs and Drupal watchdog for any errors to see if they provide a clue as to why it doesn't work
