Missing required <field name>
HOW TO RESOLVE:
Enter missing required data (required status by field indicated in third row of template) based on data type restrictions listed by field in third header row of template. Ensure each record includes values for all required field before re-uploading.

ADDED EXPLANATION:
Surveys must include key fields that answer "where, what, when, and who" questions: either a 'GRTS Cell Id' or 'Latitude'/'Longitude' to locate the survey; a 'Site Name' to describe the place; 'Survey Start Time' and 'Survey End Time'; the the 'Name of Surveyor(s)'. Each survey type may also require a few additional fields. If any required fields are omitted, the upload wizard will block the file or flag row-level omissions. Use the template's informational header rows to see which fields are required and ensure each data entry row contains entries for these fields before uploading.
