How do I remove a comment, note, or ?

[kydan47]

Received a spreadsheet with these annoying pop up boxes that the boxes stay
up until I move the cursor to an unaffected cell. Appears to be attached to
a range of individual cells. Can move the comment, note or ? anywhere on the
spreadsheet, not outside of spreadsheet.

Looks like a comment or note, but no cell indicator on corner of cell, and
the insert comment command pops up a box for a comment insertion. Have tried
"no comments or indicators", "no smart tags".

Anyone have an idea of what I've got, AND how to get rid of them?

Thanks in advance, and

Any help appreciated.

Thanks all, but I found the answer on a different post. Apparently, their is
a popup message under Data, validation.
