Adapt Agoda Affiliate Searchbox - to function in Html5 mode

We have the Agoda Affiliate Searchbox on our webpage, which is PHP. I think the Searchbox uses AJAX script to generate the subsequent link to Agoda. However, in Html5 mode - the Searchbox does not even appear on the webpage. We need a person who can make the Searchbox appear in Html5 mode, and function as on a normal webpage, but in Html5 mode. Small project for a person experienced with the Agoda Searchbox, and understands Html5 - offering $30 for immediate completion. Only persons who know exactly what the issue is, and how to immediately resolve this - should respond.
