On the Quality/Temperature Log task lists you must select Pass, Fail or N/A for each task. You must also enter a temperature for any tasks that require it. If the temperature is outside the acceptable range the task will automatically fail.
On the Checklist task lists you do not need to check each item before you submit the task list. In this case, you should check all of the tasks you completed while leaving the tasks you did not complete unchecked. You will be able to submit the task list if at least one task is checked.
