Easing Slider "Lite" Blank Area instead of slideshow

My website is https://www.teachwithfergy.com and I’ve been trying to input your slideshow into my homepage. I created a different template for my home page called homepage.php and when I enter one of the codes below into the Editor, I just get a big blank space. My background is grey and that’s the color of the area where the slideshow should be.

Any help would be greatly appreciated.

<?php
if ( is_front_page() && function_exists( 'easingsliderlite' ) ) {
    easingsliderlite();
}
?>

<?php
    if ( function_exists( "easingsliderlite" ) ) {
        easingsliderlite();
    }
?>
