Making it easy is the secret of improving captured data quality. When a user enters data in to a field with validation rules, please give visual feedback to show when validation is not being met, and when it is correct. e.g. when asked to type a six digit number, please colour the numbers and outline the field in red and raise some associated textual alert nearby until validation is correct, at which point the field and digits can return to the normal colour and the alert removed.

Currently only a counter is displayed which is less easy to see and not intuitive to non-technical users.
