Why can't I click the 'Next' button?
We know it's annoying: you finish a task, but the Next button isn't active and you can't submit it.
This often happens because of a problem with the way the task was done..
For example: if there's a minimum of three keywords but only one was entered, an outline was left unlabeled, or if we ask for only one bounding box but a second was accidentally started.
For these cases, please check the instructions, and complete the task, such as by removing or adding bounding boxes as needed. Clicking Undo will sometimes help find the problem.
If you're sure that everything was done correctly, please send a screenshot to firstname.lastname@example.org so we can figure out what's happening.
