How do you close/hide a div layer from a close button on the layer itself?

I have a flash video that plays in the corner of a page, and I want the user to be able to shut it whenever they would like.

My mockup is at http://www.travel4university.com/testlay…

I found code at Javascripttoolbox.com to shut a modal popup div from with in itself using a button, but it isn't working with my div layer for some reason. I know the problem is with the

Any ideas?

Instead of Popup.hide('video') do

onClick=”var lyr =

document.getElementById('video');

lyr.style.display='none';”

however the video might still be playing while the layer is hidden

So this is better:

onClick=”var lyr =

document.getElementById('video');

lyr.innerHTML='';”

Note the ='' are two single quotes
