Dear Duarte
Thanks for your message and sorry you are still having problems.
We received your video - however it only seemed to be 1 second long so we couldn't really see what was going on.
However, we did notice that you are using Excel for Mac and to be honest with you we have not tested the spreadsheet on the Mac version of Excel.
We quickly tested the version received in your email in Excel 2010 and Excel 365 Windows and it works perfectly (we are happy to make another quick video adding your hotel if you are interested).
Finally, if you are unable to get this working we are very happy to refund your purchase.
Regards,
