Hi.

How to make an action which depends on two triggers?

Hi, slavikss.
Yes, it's not allowed:
Note that using “And” calculation is disallowed between several triggers when they are selected as a Trigger= condition. Actions can only be executed based on the event of one trigger.

But you can create a trigger with two expressions and "and" operator.
