So I have seen the original post on how to show the last cell of a column using
=INDEX(FILTER(B:B , NOT( ISBLANK(B:B ) ) ) , ROWS( FILTER(B:B , NOT( ISBLANK(B:B ) ) ) ) )
While that works for populated cells, I have a sheet where sometimes the last cell does not have content but require that the old content be removed upon a new row being added with info. In other words. If all three columns have content each time a new row is created, all is okay and the content gets replaced; if only two columns get replaced leaving the third column empty, the referenced cell will not show a blank, and will continue to show the last entry from the third column.
Any help would be much appreciated. You guys are great!
