Two problems: 1) you want to set a single cell but the way the formula is written makes it a column formula and 2) the rows as written include the header line and go all the way to the bottom - assuming you want the two rows after the "Averages" row, you can say #+TBLFM: @>>>$2=vmean(@<<..@>>>>) That says "the third row from the bottom in column two is the mean of the rows in the same column, ranging from second from the top to fourth from the bottom". I thought I could use references relative to @> (e.g. @>-3) but apparently that's not the case: #+TBLFM: @>>>$2=vmean(@<<..@>-3) does not work for me. Nick
