Write the name of the event at which the trigger will work. It`s important! The name of the event must be specified exactly the same as in the trigger. Case-sensitive and without extra spaces.

Triggers work only in published versions, if you test through a draft, the trigger will not work for you.
The trigger is launched in all components, regardless of whether the person subscribed to the funnel with the trigger or not. If two components have triggers with the same name, then both triggers will fire when the event occurs. Therefore, use triggers with unique names.
