I can't move to the next module/the modules is locked - Why?

In your Hub, active Modules will show as a blue and green square and the ones you haven’t unlocked yet will be 'greyed out' with a little padlock. 

You won't be able to unlock the next module, until you have marked the previous one as completed.

To mark a module as complete, open the module, go to the bottom of the page and click on the button below  'Module Completed? 

Remember - the system tracks your progress based on completing entire modules, rather than your daily activities within a module, so you'll see your progress bar update each time you complete a module.
