Javascript and HTML code shows odd

I am trying to put the code below to install a search engine, it looks odd and messy. Tried javascript widget, but it doesn’t help. Tried in other themes, no such problems. Please help, as my client really fancy your theme. Thanks

<script type=”text/javascript”>
idReferral=; //This is your referral id
search_type=1;
</script>
<script type=”text/javascript” src=”//www.travelgrove.com/affiliates/javascript/search_box_new.js”>
</script>
<div style=”position: relative; top: -245px; left: 238px; font-size: 12px; font-style: italic; text-align: center; width: 100px;”>Powered by
