add map element, choose host, then select a template.
two problems here.

1. a template can be chosen as a map element - that doesn't seem to make much sense and should be prevented;

2. Use of undefined constant S_TEMPLATE_SMALL - assumed 'S_TEMPLATE_SMALL' in /usr/local/apache2/htdocs/trunk/include/maps.inc.php on line 694, referer: http://localhost/trunk/sysmap.php
