Hello, when you submitted your September solution to the form you were requested to submit the data you used too.

You can use the more up-to-date data and submit that with your solution. You can't add a new dataset though. If you used data A, B, C for your September solution, then you must use A, B, C for your October submission. You can use the most up to date version of data A, B, C. Do not add dataset D to your October submission as dataset D was not in your September submission.
