Please excuse the delay; I injured my back shortly after making the post, which put me out for a few days.

My spreadsheet that I received had column titles in which two rows were shown to take up one cell. Or, the titles took up the entire cell, despite the cell having a height that amounted to two rows.

I finally came upon Format Cells/Alignment/Text Control: uncheck Merge Cells. This did the trick. I was back to being able to use each row to a cell.

Sorry for the confusion. But, I appreciate the responses.

Ah, your problem was even more straightforward than I guessed. Funny thing is, shortly afterward, I found myself tackling a similar spreadsheet which has items on two rows instead of one. Glad you worked it out.
