Sorry Jason - not sure what I've done wrong now, but I've managed to break it again.
It was working OK, and I was looking at why there was no bar, and realised the same bug must have prevented adding the link to:
So I added that, but after I uploaded it, it didn't work.
I should have downloaded the copy you uploaded, but if all you changed was that line above to reference that .js file then I'm not sure what happened.
I've just spent a bit of time retracing steps, starting from scratch, but can't get it to work again.
Sorry to be a pain, but could you have another look please? Thanks.
