ZoneMinder Forums

I have been using zoneminder for 5+ years now and usually find answers to all my issues via searching the forums or the wiki, but this one is stumping me. I want to execute an external action when an event is triggered, google directed me to http://www.zoneminder.com/wiki/index.ph ... n_alarm.3F

I try it but I get

Undefined subroutine &main::zmDbgInit called at ./zm_alert.pl line 9.

Any ideas?

Thanks
