Javascript conflict only in Chrome

With my template occurs this error on this menu:
https://sandkiste.flute.at/werkstatt.html (as well as on subpages)

Uncaught TypeError: $.scrollTo is not a function
at originalScrollTo (common.js:9)

I've added this script to the bottom of my index.php:

<script type="text/javascript">
	// http://html-tuts.com/back-to-top-button-jquery/
	// create the back to top button
jQuery(document).ready(function(){
	
jQuery('body').prepend('<a href="#" class="back-to-top btn no-btn btn-sm hidden-sm hidden-xs"><i class="fa fa-arrow-circle-up" aria-hidden="true"></i>Back to Top</a>');

var amountScrolled = 200;
	
	jQuery(window).scroll(function() {
		if ( jQuery(window).scrollTop() > amountScrolled ) {
			jQuery('a.back-to-top').fadeIn('slow');
		} else {
			jQuery('a.back-to-top').fadeOut('slow');
		}
	});

	jQuery('a.back-to-top, a.simple-back-to-top').click(function() {
		jQuery('html, body').animate({
			scrollTop: 0
		}, 700);
		return false;
	});
});
</script>

The error only occurs in Google Chrome.

Can you give me some help to solve this issue? Thank you!
