You set repeats when you create the eScript, choosing how many repeats are allowed and the minimum time between them.
Each repeat is dispensed against the same eScript, up to the limit you set, and its status is tracked through to dispensing. When an eScript token is sent to the animal owner, the number of repeats remaining is shown on the token.
To stop any remaining repeats, cancel the eScript. This ceases all repeats associated with it, so no further dispenses can be made. See "Cancelling an eScript."
