Error submitting collected data into the server

The Post distribution monitoring assessment was done before uploading the data collection tool into the server now there is challenge uploading the completed forms into the server. I have tried several options but failed am afraid the staff made some mistake of not uploading the tool to the server first. Any technical help to send the data into the server.

@samamer_consulting, would you mind following the instructions as outlined in this support article Manually Uploading Submissions to see if you can upload the submissions manually to the server?
