Fatal error: Call to undefined function putRevSlider()

Hi BlueOwl.
I made some changes in my site, and I don’t use RevSlider plugin any more.
I deactivated and uninstalled the plugin, but an error appears: Fatal error: Call to undefined function putRevSlider()
So, to fix it, I modified the file index.php, row 37.
This is what I did:
I changed from this

<div class="twelve columns">
			    <?php putRevSlider('80s-style-intro', '569'); ?>
				<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

to this

<div class="twelve columns">
				<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>

Please, can you tell me if it’s correct?
Thank you.
