[Plugin: WP Stock Ticker] Need Help on Where to Insert Code

I am using the WP Stock Ticker plugin and want it displayed on the the top of my page.

Here is the code I’m supposed to place in the page to have it display:

if(method_exists(‘WPStockTicker’, ‘s_ticker_display’)) {
$xx = new WPStockTicker();
echo $xx->s_ticker_display();
}

Unfortunately I don’t know where to enter this code. I went to functions.php and inserted it in a line there but after doing so it crashed my page. The ticker briefly appeared on the website, but for some reason I wasn’t able to get into dashboard and my site wouldn’t even load for me soon after.

Can someone please advise as to where to put the code so it appears on top of the website properly?

I am running the MxS2 theme. Here’s a link to my site:
