Remove slider from all sites except homepage

So i have this Slider that i only want on my homepage, but for some reason it will not move from all the other pages, and i asked it really nicely. so do someone have an idear what to do?

My theme is storefront, slider plugin metaslider, and i have added

<?php do_action( ‘storefront_after_header’ ); ?> in header.php

and

add_action( ‘init’, ‘child_theme_init’ );
function child_theme_init() {
add_action( ‘storefront_after_header’, ‘woa_add_full_slider’, 5 );
}

function woa_add_full_slider() { ?>
<div id=”slider”>
<?php echo do_shortcode(“[metaslider id=168 percentwidth=100]”); ?>
</div>
<?php
}
in functions.php

and i would like something more to remove the slide from all the other pages then the homepage.
