Order priority is an 'advanced user' setting (recommended for those with a strong knowledge of how the timeline works). The lower the number means the higher the priority. Therefore, if two questions are on the same level in the timeline then the question with the highest priority (lowest order priority number) will be received first by the respondent. The order priority number can be between 1 and 99. The default order priority is 50.
