# CannotEndInPast (/docs/errors/chain/CannotEndInPast)

The `end` block passed to `create` or `update_end` is not after the current block. Compare the `end` argument against the current block number; it must be strictly greater.

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

Declared at [`pallets/crowdloan/src/lib.rs#L247`](/code/pallets/crowdloan/src/lib.rs#L247).
