If i understand you the right way. you want to jump from page-A to page-B [copy&paste the valued Dropdown-data from page-A (non-dynamic-page) to page-B(dynamic-page)] ?
On page-B you then want to put the data into your search-engine to get some results out of your Properties3 database?
And i assume that you will delete all 3-buttons on your page-B later, right?
Either it does not make any sence to have 2x the same setup on 2-sites.
You have to choose on page-A and then to choose again on page-B ?
