Why can't I save my new spreadsheet?

I have a one page spreadsheet of calculations that I would like to keep but I can’t make it save.

Can you list the steps you are taking? And tell us what OS you using, version of LibreOffice and what file type you are trying to save it to (ods, xls)?

Also, what is the exact error message and where are you trying to save it. Try selecting another folder.
