see if this works. Put all the content of the first page inside one div and the same with page two. Then make a link or a button to go to the second page, but what this is going to do is hide the div of the first page and show the div with the second page fields
onclick="document.getElementById('firstDiv').style.display='none';
document.getElementById('secondDiv').style.display='inline';"
by doing this you dont need to pass values from one page to another and everything will be sent as if it was a one page form.
