Dynamic dependent dropdown search test page

I have set up a Dynamic dependent dropdown search test page but when I do a search I cannot get the correct results on the results page, any help would appreciated.
The test page is http://gosfordparkcl.co.uk/ and the results page is http://gosfordparkcl.co.uk/test.php

Your second two select lists don't have a name attribute. The name is what is used in the form submit and would be necessary to filter any results.

Hello Ray and thank you for your speedy reply. I have included the names for the 3 select boxes but still no filtering.
Where is it I include the attribute names to get the filtering working?

I'd have to see a copy of the results page where the filtering occurs to see where it is set. For all I know the filter code isn't even on that page. How did you intend it to work? What did you do on the results page to apply the filter?

Hello Again Ray, the filtering is just a test page attached

So this page only filters with one column value: $_GET['City']

There are a few issues with that.
1) Your form uses post not get
2) Your form element is named "city", not "City"
3) Your code that dynamically updates the select lists seems to also remove the name attribute from the city select list entirely.

All of those things would have to be corrected before your search would work.

Filtering

Update ajax.php. Change line 14 from:
echo "<select id='statedd' onchange='change_state()'>";

to:
echo "<select id='statedd' name="state" onchange='change_state()'>";

and change line 29 from:
echo "<select>";

to:
echo "<select name='city'>";

Hello Ray, Working just perfect.
Many thanks for your excellent help.
Kindest regards Nicholas

Hello Ray,
I have a slight problem with my results page. When I click the next tab at the bottom of the page I get back all results from my database and not the next 10 results. The full list comes back no matter what the first results are, even if I only get back say 2 results from the search and click the next tab I get back the full list. If I go back to the First tab I get the same full list. Search file and results file attached
