Appart from Navaldesign DBTS form processor is there any other way to create a survey form on multiple pages? Thanks.

Yes you can. The suite is both compatible with x32 and x64 bit software.

It is not recommended to use background music on a website because you are forcing the visitor to listen to it, as soon as I heard the music I tried to disable it faster.

You will get a one page shop with many features and a lot of payment gateway providers. You will get a dedicated link and you can sell even you do not have a website. If you want to integrate the shopping page use an iframe.

There is a ready extension available on http://lucknowwebs.com/cms-shopping-car ... and-above/
or a script that you can integrate in your website available on https://www.phpjabbers.com/php-shopping-cart-script/

Yes, freezes at the contact form.

Same issue on smartphone, it freezes at the half.

I would set the menu fixed and the back to top arrow too, going up and down distracts the visitors attention.(on smartphone layout)

Problem persists on smartphone, the menu button is not visible.

It happens on desktop too if you scroll to the right.
