I don't understand what is causing you a problem but there is an easy failsafe. Spreadsheet is open this season, meaning anyone can look at it and see if they submitted.

As soon as you click send there is your name and timestamp shown in sheet while your answers are hidden. Just check if it is there.

We wrote about it before and i am double checking my entry every time. If anyone has problems contact us before the deadline. After deadline passes there is nothing we can do anymore.
