Drupal Single Quote Problem

Hello Forum,

I am building a hook_link for my module, however my URL string has a several single quotes. When I do a view source in the browser the single quotes are replaced with '

For example:

onclick="Subscribe(1517,645,2726,'Drupal Forum Node 1','','','');" class="elertz_link_url">

Should look like

Subscribe(1517,645,2726,'Drupal Forum Node 2','','','');

This is my code:

/**
 * Implementation of hook_link().
 */
 drupal_set_html_head('<script src="http://www.elertz.com/flashclient/subscribe.js" type="text/javascript"></script>');
 drupal_set_html_head('<script type="text/javascript">addSubJS();</script>');
 function elertz_link($type, $node = 0, $main = 0){
 $img_elertz_merecat = drupal_get_path('module', 'elertz') .'/images/elertz_16x16.gif';
 $elertz_url_title = variable_get('elertz_url_title',"");
 $nid = $node-> nid;
 $elertz_subscription_code = variable_get('elertz_subscription_code',""); 
 $schema_id = variable_get('elertz_schema_id',"");
 $webmaster_id = variable_get('elertz_webmaster_id',"");
 $elertz_brand_id = variable_get('elertz_brand_id',"");
 $elertz_subscription = ("Subscribe("
 .$webmaster_id.","
 .$elertz_brand_id.","
 .$schema_id.","."'"
 .$elertz_subscription_code." Node ".$nid."'"
 .",'','','');");
 
 
 $links = array();
  
  if ($type == 'node' && $node->type == 'story' || $node->type == 'page' || $node->type =='blog'  ) {
    if (arg(0) != 'story' || arg(1) != $node->uid) {
      $links['elertz_link_url'] = array(
        //'title' =>  t($elertz_url_title),
        'title' =>  t($elertz_subscription),
        'href' => "",
        'attributes' => array('onclick' => $elertz_subscription),
        'html' => TRUE,      
      );
    }
  }

  return $links;
  
  
 }
