A rule is not firing

Start with the run history, not with the rule. It shows what actually fired and what happened, which separates "never triggered" from "triggered and failed" — two problems with nothing in common.

Filter it by rule and by outcome using Alle utfall. Note that Ingen kjøringer ennå. Tørrkjøringer og nattlige helsesjekker telles ikke her. — test runs and health checks are excluded, so an empty history means no real event has matched.

Nothing in the history at all

The trigger never matched. In order of likelihood:

1. 1The rule is not active. It has to be set Aktiv to run at all.
2. 2The event does not exist for that record type. Events are not shared between types, and choosing one that does not apply produces a rule that saves happily and never runs. Check "What can trigger a rule".
3. 3A condition is excluding everything. Conditions combine, so each one narrows further; one wrong value and nothing qualifies. Take them off one at a time to find which.
4. 4Nothing has actually happened yet. A rule only fires on events after it was created. It does not run over records that already met the conditions before it existed.

Runs are there but failed

{{count}} feilede kjøringer på denne siden. Open the failed run — it says which action failed and why. The usual causes are an action referring to a field that has since been renamed or removed, an email action with no valid recipient on the record, or an action that needs a linked record the triggering record does not have.

It fires, but nobody sees the result

Usually a task created without being linked to a record, so it never appears on the customer where someone would find it. Add the link on the action — see "What a rule can do".
