# studio-cancel-outside-before

> *Cancel the action* appears outside an *about to use* row.

| Kind | Studio problem |
| Reported by | Studio validation: the Problems panel, Play, Publish and the MCP `validate` tool |
| Code in the Studio | `cancel-outside-before` |

Only an _about to use an action_ trigger runs before the engine applies the action, so only there can it be cancelled.

## Fix

- Move the cancel into an _about to use_ row, or remove it.
