Problem
The form shows an error about locks after you switched on Limit lock access.
Possible cause
When the Limit lock access toggle is switched on, you must select at least one lock from the dropdown. If no lock is selected, the form will not submit. It may also be because the system has no configured locks.
Solution
Check that you have selected at least one lock from the Lock ID dropdown.
If the dropdown is empty, your system may have no configured locks — set up locks in the Centre settings first.
If you do not need to restrict lock access, switch the toggle off again.
If the problem persists, contact support and include details about:
Whether locks are configured in the system.
