How do I translate taxonomy terms in a block?

Hello!

I am building a Navigation-Block of all taxonomy terms in a vocabulary to be used for navigation as follows:

<?php
$vid = 1;
$terms = taxonomy_get_children(0, $vid);
if (count($terms)) {
echo "

";
foreach ($terms as $term){
$activeMenu = "";
if ((isset($_GET["tid"])) && ($_GET["tid"] == $term->tid)){
$activeMenu = "class='active'";
}
echo "
• tid . "' " . $activeMenu . ">". t($term->name) . "";
  echo "

";
}
echo '

';
}

(http://noradreissigacker.com/en/works)

This works fine, but I am unable to show the translation of the terms when I change the language. I have tried to do it with t($term->name) but this does not work.
I have also tried the Taxonomy Navigator Module but encounter the same problem there.

Translation mode of the vocabulary is ' Localize terms. Terms are common for all languages, but their name and description may be localized.'

Can someone tell me how this is done?

Thanx
