Undefined variable: rows [include/triggers.inc.php:301]

when creating a new service (config-->IT Services) i get:

Undefined variable: rows [include/triggers.inc.php:301]

Zabbix 1.9.9

Not sure if it's a bug or i'm doing something wrong. I never used this feature in 1.8 but plan to when zabbix 2.0 is released.

while that's a different page, i suspect the underlying cause is the same as for https://support.zabbix.com/browse/ZBX-4596
