vslider plugin

trying to insert vslider plugin into header with if then statement

<?php if ( ‘dt_vslider’== yes vslider(‘dt_vslider_name’); ?>

created dt_vslider in custom field of page and created dt_vslider_name in custom field of page so that I can use different vsliders slides in different headers. I need to have the vslider as the header below the menus. Page is https://www.stwtc.org.

Can someone let me know 1. can this be done and 2. am I doing it right. I know my syntax is way off. Appreciate the help.
