Why can't I click the 'Next' button?
Sometimes the Next button won't be active in a task. This often happens because of a problem with the submission. For example: if there's a minimum of three keywords but only one was entered, or if we ask for only one bounding box but a second was accidentally started.
This can also happen if there are extra spaces for a text box submission, or some other text format problem. When this happens, a task can't be submitted and the 'Next' button will be inactive.
For these cases, please check the instructions, and complete the task, such as by removing or adding bounding boxes as needed.
If you're sure that everything was done correctly, please send a screenshot to email@example.com so we can better figure out what's happening.
