 * [2 years, 7 months ago](https://wordpress.org/support/topic/validating-interest-groups/)
 * I’m creating Custom Form Validation using the example code below.
 * When I replace ‘some-field’ with a TEXT field it works however attempting to 
   use an INTEREST GROUP VALUE it gives an error regardless what value is posted
   in the Form.
 * I’ve tried several variations of **$_POST[‘INTERESTS[d8cc6bc082]’] !== ‘3af0a91e25’)**
 * What is the correct Syntax for INTEREST GROUPS?
 * /** * Performs additional form validation on Mailchimp for WP forms * * [@return](https://wordpress.org/support/users/return/)
   array An array of error codes. */
 * **function** myprefix_validate_mc4wp_form($errors) { _// perform validation here_**
   if**( $_POST[‘some-field’] **!==** ‘expected-value’ ) { $errors[] **=** ‘incorrect_value’;}**
   return** $errors; }
 * **add_filter**(‘mc4wp_form_errors’, ‘myprefix_validate_mc4wp_form’);
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fvalidating-interest-groups%2F%3Foutput_format%3Dmd&locale=en_US)

 * I think it would be
   $_POST[‘INTERESTS’][d8cc6bc082] !== ‘3af0a91e25’
 * Hope that helps. If you have any questions, please let me know!
