JavaScript not showing on website

Hi, 

Please help - I've added some javascript to a code block on a page in our website (site is not live so is password protected). The code has apparently been tested in SquareSpace by the supplier and they've confirmed it works - but I can't get it to work. No matter what I do the page is blank when I view it when logged out of admin. We are on a business plan. Any ideas - could it be a setting in our site that I need to change? 

This is the javascript:

<script type="text/javascript">
window.onload = function () {
var wd_iframeWin = document.getElementById("wd_ediary_iframe").contentWindow;
wd_iframeWin.postMessage(JSON.stringify({"browser_url": window.top.location.href}), "*");
};
</script>

<script src=https://ocucowebdiary.net/widget?key=08118c918c4fd5de15ffc2cfa337ebde&type=js&clear=1></script>

Thanks

Thanks I did go back to them in the end and they've sent new code which actually works!
