Contact form welcome massage problem in popup box

I'm using Contact Form 7 Plugin in easy fancybox. it's working fine.

I'm using it in http://ift.tt/1M2FOYW this site.

When visitor click on "REQURST QUERT" Button then show contact form in a light box and when click send button of the contact form then show welcome massage it's ok. But when I clicked another "REQURST QUERT" Button then the welcome massage is still.

So when click anther "REQURST QUERT" Button then I want show new contact form without welcome massage.
