Trouble with ConciseSpreadsheet

To list,

I’m having trouble getting my ConciseSpreadsheet extension working. We
installed “ConciseSpreadsheet” into /share/html. However, I can’t find
any instructions on what to do after that. I had some old instructions
for 3.6.4, but they can’t apply because the code in “Results.html” has
changed too much. Can anyone help me on this? Thanks.
