In libreoofice 4.2.5 search and replace

Doing a simple spreadsheet for keeping track of household grocery expenses.
I can’t seem to do search and replace to change some of the entries in a text column, and
I can’t get quotient to work. I did search the help sections and got no good ideas there
Thanks

I think not easy to find out the issue without a sample file. Can you share one?, Please delete any personal information.

You can call the search function with CTRL+F. It will be shown at the bottom of the sheet/screen. There you should be able to see an image resembling a Q crossed by a pencil. Click on it and a new, small window will open, showing the search and replace fields. I hope this helps. Cheers!
