Larry:
You are making this more complicated than it needs to be.
I simply have an index page that contains a div to hold the three selection controls (state/cit/zip).
I use another php script (get.php) to present/populate the selection controls AND gather the data needed.
The selection controls trigger the ajax routine like so:
<select name="state" onchange="javascript:get(this.parentNode);">
The ajax routine sends the value selected to the get.php script which in-turn repopulates the selection controls.
Repeat and rinse.

PS: Why use framesets?
