body: <p>How would i populate an Opportunity custom field? using iSDK</p>
  
  <p>everytime i try to add one, it populates the Contact custom field and not the one on opportunities</p>
  
  <p>the name of my custom field in opportunity is <code>message_form</code>, database is <code>messageform</code></p>
  
  <p>here is my relevant code</p>
  
  <pre><code>$oppor = array(
  'Email'=&gt;'greatest@mail.com',
  '_messageform'=&gt;'lorem ipsum dolo'
  );
  //action ID is set to add opportunity
  $actionId = 224;
  
  $newCon = $app-&gt;addCon($oppor);
  //run an action set on the contact
  $stat = $app-&gt;runAS($newCon, $actionId);
  </code></pre>
