Implementing redirect feature on individual wordpress page

Hi Benjamin,

I am trying to implement this feature “Redirect depending on country” mentioned in the following page.

What I did was as follows:
1) Create a custompaget1.php script as shown below.
2) This script would reside in my public_html/wp-content/themes/directory2-child
3) Create a new page in wordpress using the above script

However, the redirecting does not seem to work. I get a blank page when I load up the page. My aim is to create redirects for particular pages within wordpress.

Thank you.

<?php /* Template Name: CustomPageT1 */ ?>

<?php

add_action('template_redirect', 'geoip_redirect', 5);
function geoip_redirect(){
	if (is_admin())
		return;

	// This condition prevents a redirect loop:
	// Redirect only if the home page is called. Change this condition to the specific page or URL you need.
	if (!is_home())
		return;

	if (!function_exists('geoip_detect2_get_info_from_current_ip'))
		return;

	$userInfo = geoip_detect2_get_info_from_current_ip();
	$countryCode = $userInfo->country->isoCode;
	switch ($countryCode) {
		case 'DE':
			$url = '/germany';
			break;
		case 'US':
			$url = '/usa';
			break;
		case 'SG':
			$url = 'www.google.com';
			break;
		default:
			$url = 'www.google.com';
	}
	if ($url) {
		wp_redirect(get_site_url(null, $url));
		exit;
	}
}
