show fields not data into theme

Hello we are a ONG and recently buy a theme at themeforest crowdspeaking theme view page

it has just one field to describe the entire project project but we want Operador, Área de impacto, Ambito de accion, Objetivos específicos, Beneficiarios, etc as independent fields

so i download pods and extend this project category blog in the backend page and voala we have those fields in the backend

now we want to display those fields to a user can fill with text and save then display the content in this field in another page

in my theme are 2 pages i think are the main responsible for this

tmp-campaign.php for fields code example of one field: `<label for=”postContent”><?php _e(‘Campaign message:’, ‘reach’) ?></label>
<textarea name=”postContent” id=”postContent” class=”countCon” maxlength=”115″><?php if(isset($campaign_content)) echo $campaign_content;?></textarea>`

and single-campaigns.php to show the field contents code example of showing the content v

<div id="story" class="tab-pane active"><p>
<?php echo apply_filters('the_content', $story); ?></p></div>

so i stuck here and we want to know if you can give us a clue how to start showing this fields the part of showing the contet we found easy thanks in advance and sorry for my bad eanglish
