Simple Text Widget and adding in javascipt

I added some javascript into my sidebar to open an image in a resizeable popup window. It was working fine and then all of a sudden has stopped working.

Before I had the code working, i took some code I had on an existing site to see if that would work – which it did, then altered the existing code according to this. Now both are not working, its the strangest thing…any suggestions.

Here is my code…

<script type=”text/javascript”>
// Popup window code
function newPopup(url) {
popupWindow = window.open(
url,’popUpWindow’,’height=255,width=480,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes’)
}
</script>
