Double Scroll

Hello,

my site http://indiatravelz.com has two vertical scrollbars, one of the hardly scrolls at all, the second one is fine.
I’ve tried writing the code:
html {
overflow-y:hidden;
}
In the Quick CSS box in styling under Enfold options, but what happend is the the normal scrollbars was gone and all was left was the scrollbar that didn’t move at all.

Please help
