Please use the code tags to put code on here.

From the information you provided it would not be possible to tell you what the issue is:
1. You have not said what is and what is not working
2. In the code you have posted you are using objects/variables which are not defined or described

In order to help we would need to know what the script is supposed to do and be able to see the classes and procedures used to populate the variables mentioned above.

thanks you, I create three dropdown list for region, province and by cities, the first dropdown list is used for the region, if i select from the region the second selector will display the list of province according to region and at desame time my cities list selector will also change according to province i select too. probably i done it well but, the problem i could not get the value to display on selected list.
here are the part of my code.

<?php
		switch($select) {
			case "city": {
				if ($select!=all) {
					$city=$select;
					$select="city";
				}
				else
					$city=$select;
				$heading="Hotels for \"".city::getDisplayName($city)."\"";
				$hotelsToShow=hotel::getForCity($city);
				break;
			}
			case "region": {
				if ($select!=all) {
					$region=$select;
					$select="region";
				}
				else
					$region=$select;
				break;
				$heading="Hotels for \"".city::getDisplayName($region)."\"";
				$hotelsToShow=hotel::getForRegion($region);
				break;
			}
			case "province": {
				if ($select!=all) {
					$province=$select;
					$select="province";
				}
				else
					$province=$select;
				break;
				$heading="Hotels for \"".city::getDisplayName($select)."\"";
				$hotelsToShow=hotel::getForProvince($select);
				break;
			}
			case "all": {
				$heading="";
				$hotelsToShow=hotel::getAll();
