I'm desperately trying to grab this website:

<http://www.chartstats.com/>

However, to get the charts I need, the user must click the "ChartArchive ON"
button on the bottom right hand corner of the screen.

How do I do this with httrack?  Whenever I try and grab, I get the site
*without* the charts.

Can someone please help me before the site disappears forever!

Thank you.
