title: Modifying the logic around the global variables in BigCommerce
body: <p>I am new to BigCommerce platform.I came to know that the global variables in big commerce got its values from the logic that comes from PHP classes from somewhere <strong>includes/classes folder</strong>.  </p>
  
  <p>My problem is I couldn't get access to those files.I want to know whether i can get access to those files,if yes than how?</p>
  
  <p>Actually i wanted to use my logic on product option.On inspection i found out that it is rendering from this global variable.</p>
  
  <blockquote>
    <p>%%GLOBAL_ProductAttributeList%%</p>
  </blockquote>
  
  <p>Till now i only could modify the template files.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Thanks in advance.</p>
