How do you properly use JavaScript in Text Gadget?

Hey there,

 

I'm trying to add more content to my JIRA dashboard by using the HTML capabilities of the "Text Gadget". Things seem to run great the first time, but I get an "Unknown error occurred rendering this gadget" if I try to edit the gadget's content.

 

Here's the specific JS I'm adding:

<h3><div id=”milestone_countdown”></div> days left!</h3>

<script>
today=new Date();
var next_milestone=new Date(today.getFullYear(), 10, 12);
var one_day=1000*60*60*24;
document.getElementById("milestone_countdown").innerHTML = Math.ceil((next_milestone.getTime()-today.getTime())/(one_day));
</script>

 

And the error I'm getting when I inspect the element in the page:

Uncaught TypeError: Cannot set property 'innerHTML' of null
Error rendering gadget with id '15053': Cannot set property 'innerHTML' of null TypeError: Cannot set property 'innerHTML' of null

 

What am I doing wrong and how can I fix this?  Thanks!
