GTM Script Blocking Error

Hello,

I’ trying to add:

<?php if ( function_exists( 'gtm4wp_the_gtm_tag' ) ) { gtm4wp_the_gtm_tag(); } ?>

to the body section of the script blocking, but it must not have accepted the code as is because the code is not there anymore…just white space.

I’m using GTM for my google analytics code so I needed to add that to the script blocking. Soooo……

Is there something I’m doing wrong with this code when I place it into the script blocking? I’m really new at this.

Thanks!
