I tried registering my Student/Staff ID but got an error. What do I do ?

The CellOPark system validates the student/staff  ID against the parking operator database in real time and each ID can only be used once. If the system does not allow you to register your ID you should first make sure that you haven't used it in a different account and speak to the registration office and make sure everything is valid with them. CellOPark has no control over the database and only use it for validation.
