# studio-slot-type

> A slot holds a value of the wrong type.

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

Each slot accepts one type: a number, a point, a player, a disc, one of fixed choices, a variable or a timer. The message names what the slot expects and what it got.

## Fix

- Change the value to the expected type, for example `player.team` where a team is expected.
- Pick a timer variable where the action works on timers.
