Switch currency with language change – polylang

This works perfectly for me – exept for the check out page.. Here it allways show the price in origin currency ??
What do it do?

This is the code:

add_filter(‘wp_head’, function() {
$lang = get_locale();
global $WOOCS;
switch ($lang)
{
case ‘da_DK’:
$WOOCS->current_currency = ‘DKK’;
$WOOCS->storage->set_val(‘woocs_current_currency’, ‘DKK’);
break;
case ‘en_GB’:
$WOOCS->current_currency = ‘EUR’;
$WOOCS->storage->set_val(‘woocs_current_currency’, ‘EUR’);
break;
default:
$WOOCS->current_currency = ‘DKK’;
$WOOCS->storage->set_val(‘woocs_current_currency’, ‘DKK’);
break;
}
});

What am i doing wrong?
