Script code in Avia layout builder

I am trying to embed a wufoo form on my site, and every time I paste the script code it crashes the page and won’t let me use it, presumably because it is trying to load a preview. How can this be fixed? I have done this a hundred times on other sites and never had a problem. Here is the code I am trying to paste in:

<script type=”text/javascript”>var host = ((“https:” == document.location.protocol) ? “https://secure.&#8221; : “http://&#8221;);document.write(unescape(“%3Cscript src='” + host + “wufoo.com/scripts/embed/form.js’ type=’text/javascript’%3E%3C/script%3E”));</script>

<script type=”text/javascript”>

var w7p6s9 = new WufooForm();

w7p6s9.initialize({

‘userName’:’creativestream’,

‘formHash’:’w7p6s9′,

‘autoResize’:true,

‘height’:’577′,

‘header’:’show’,

‘ssl’:false});

w7p6s9.display();

</script>
