Hello,
Is your action still not firing? I may be able to help if you can give me a detailed explanation of your event if you are still unable to get it to fire. I could try to re-create it here:
What category is the event,
what type is the event,
what conditions do you have for the event,
what action do you have for the event,
what is the frequency of the action (if applicable)
Thanks and good luck!
