Windows Event Log Details in Email

Hi all, New to SAM here, about to purchase to upgrade Ipmonitor.

I've figured out how to make a Windows Event Log trigger on Errors , but I'm trying to figure out how i can include some details from the actual error such as Event ID , Event Description,  Etc.

I'm just trying SAM RC with the new web based alerts... When i got to INSERT Variable into my Email Action Message, I cant find the  WindowsEventMessages variable referenced in the below thread.

Configuring "Windows Event Log Monitor" alerting

I'm sure I'm doing this wrong so hopefully someone can tell me what to do.

thanks!
