I have a selection process where you choose a country, the it sets up the option for state, and then city.

What i am needing to do is set country to united states by default and still allow you to choose state and city.

The id for united states is 1 in the database.

Code:
$countryObj = new LocationCountry();
	$countries  = $countryObj->retrieveAllCountries();

	if($_GET["country_id"]== 0) {
		$stateObj= new LocationState();
		$stateObj->SetString("country_id",$_GET["country_id"]);
		$selected_states = $stateObj->retrieveStatesByCountry();
		} else {
		$_GET['country_id']."".$_GET['United States'];
		}

	if($_GET["state_id"]) {
		$regionObj= new LocationRegion();
		$regionObj->SetString("state_id",$_GET["state_id"]);
		$selected_regions = $regionObj->retrieveRegionsByState();
	}

	if($_GET["region_id"]) {
		$cityObj= new LocationCity();
		$cityObj->SetString("region_id",$_GET["region_id"]);
		$selected_cities = $cityObj->retrieveCitiesByRegion();
	}

	if($_GET["city_id"]) {
		$areaObj= new LocationArea();
		$areaObj->SetString("city_id",$_GET["city_id"]);
		$selected_areas = $areaObj->retrieveAreasByCity();
	}

	$selected_country = ($_GET["country_id"]) ? new LocationCountry($_GET["country_id"]) : FALSE;
	$selected_state   = ($_GET["state_id"])   ? new LocationState($_GET["state_id"])     : FALSE;
	$selected_region  = ($_GET["region_id"])  ? new LocationRegion($_GET["region_id"])   : FALSE;
	$selected_city    = ($_GET["city_id"])    ? new LocationCity($_GET["city_id"])       : FALSE;
	$selected_area    = ($_GET["area_id"])    ? new LocationArea($_GET["area_id"])       : FALSE;
