Defining overdue actions for default overdue actions

Delay is the number of days after an issue is due before an action is triggered.

If you want Koha to trigger an action (send a letter or debar member), a delay value is required.

Columns must be filled left to right: if the first column is blank, other columns will be ignored.

The following fields have a forbidden value. Correct them and press OK again :

Delay for borrower category has some unexpected characters. There should be only numerical characters.
Delay1 should be less than Delay2 which should be less than Delay3 for borrower category
