Finding my Google Analytics Code

Now what exactly do i input into the textbox entitled "Enter your Google Analytics Code"? I dont know where i can find my Google Analytics code which could fit into this singular line textbox. Should i deduce from the below code that my Google Analytics Code is ... UA-72837-1

<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "UA-72837-1";
urchinTracker();
</script>

Yes
