As standard, all pages within your workbook are inactive to begin. They only become activated when you have viewed the page and begin to fill them in.
If you have not yet viewed a page in your Pebble+, your mentor or tutor won’t be able to validate it. The assessor fields they require will not appear, for them to complete.
To resolve this, simply open the page in Pebble+, read the contents and save your workbook. You don’t need to type anything on the page, or complete one of the student fields, simply open the page and it will be activated.
