# Linked scenarios of a Link’nX action, condition or trigger

Context: Link’nX web: Actions, Conditions, Triggers and Scenarios lists

In Link’nX, an action, a condition or a trigger can be used in several scenarios. The chain-link icon of each item shows the scenarios that use it: check it to identify the scenarios to review before changing or removing a shared item.

Intended for administrators and installers.

## Show the scenarios that use an item

1. Open **Triggers**, **Conditions** or **Actions** and [find the item in the list](https://wiki.can-nx.com/en/guides/link-lists/).
2. If **Select** mode is active, click **Cancel Selection** to get the row buttons back.
3. To the right of the item, click the chain-link icon with the tooltip **Show scenarios using this element**. A number accompanies the links when at least one scenario is shown as linked.
4. The **Scenarios using this element** window lists their names. Note the scenarios to check, then click **Close**.
5. To view a listed scenario, open **Scenarios** and search for its name, in the same project and the same gateway (see [the access guide](https://wiki.can-nx.com/en/guides/link-access/)).

A crossed-out link icon, without a number, shows **This element is not used in any scenario.** The window may repeat this message. This check covers the configuration of the scenarios shown for this context, not the physical state of the equipment.

To then change the item, follow the guide for [actions](https://wiki.can-nx.com/en/guides/link-action-edit/), [triggers](https://wiki.can-nx.com/en/guides/link-trigger-edit/) or [conditions](https://wiki.can-nx.com/en/guides/link-condition-edit/). To remove it, follow [deleting automation items](https://wiki.can-nx.com/en/guides/link-delete-elements/).

## Understand configuration warnings

| Warning | Where it appears | What to do |
| --- | --- | --- |
| **This element has no device declared!** | Warning triangle on an action or a trigger | Check the context, then the expected equipment in its **Devices** family. |
| **This scenario is missing a trigger or an action** | Warning on a scenario | Open its configuration to identify what is missing, as described in [composing a scenario](https://wiki.can-nx.com/en/guides/link-compose-scenario/). Do not run the sequence to test at random. |

## Troubleshooting

- An expected scenario is missing from the list: check the displayed project and gateway.
- A warning persists after checking, or the right association cannot be found: contact support@can-nx.com with the item’s name, the scenario, the message and the steps already taken. Do not send any password or full access link.
