Specific projects have tasks that are locked. A lock on a task means you must finish the last task before the next one unlocks. A project can have all tasks locked, meaning you have to complete each task in order, or a project may only have specific tasks locked, which require the last task to be completed before you can open the locked one.
In the screenshot below, the task “When do you drink energy drinks?” is locked because the participant has not done the first task, “Tell us a little bit about yourself.” Once the Number of Entries for this task shows a 1, the “When do you drink energy drinks?” the task will unlock.
In the below screenshot, When do you drink energy drinks is now unlocked because the first task has a submitted entry.
Please note: The above is an example showing an iPhone. The android interface is slightly different.
