# ActivityCutoffFactorMilliOutOfBounds (/docs/errors/chain/ActivityCutoffFactorMilliOutOfBounds)

The `factor_milli` argument to set the activity-cutoff factor was outside the allowed 1000-50000 per-mille range (1 to 50 tempos). Adjust the argument to fall within those bounds before resubmitting.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
