In that case, I guess there might be some Javascript error on that page. I guess you are using custom theme.
Please to use IE to debug the page to see if there is any Javascript error. When use IE browsing the page, Press F12, the dubger will appear and you can check at Console to see if there is any errors.
Or if you give us your store URL, we can also have a look at that for you.
