Email variables Usage ?

Hi all,

I'm searching to integrate some variables in my email alert from "Event Details". i want to use "1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29" OID with value JLPAR Room-202.

I always test with this key :

${evt/eventKey/1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29}

${evt/eventClassKey/1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29}

${eventSummary/event_class_key/1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29}

${eventSummary/event_key/1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29}

${evt/1.3.6.1.4.1.8744.5.23.1.2.1.1.6.29}

Doesn't work !

Thanks in Advance
