link not working on mobile

Hi there – I am using your plugin on gmskids.com and I like it, but if I’m viewing the site on a phone, the link doesn’t work. When I tap on a slide it doesn’t go to the link I’ve set. I suppose it’s possible that it’s a theme conflict, but wanted to check before I tried another plugin. Thanks.
