Hello there.

I do believe you are wanting to try and work with the Countif
function.  There's plenty of good help on that in Excel and online.

As the best advice I can / could & will give to anyone not entirely
familiar with Excel, the best way to work out long and or complex
problems is to break it down, one column (or row) at a time.

IE: If you have all your data in a list format (and the 9's & 10's you
are trying to count is in the same column, then move over a dozen or
so columns (out of your printed screen area) and use this area to hold
some calculation functions.  In one of these reserved spots enter
=COUNTIF($B6:$B100,9) and in another spot enter =COUNTIF($B6:B100,10)
and lastly in another column sum up the two cells and viola!  Mission
Accomplished.

Hope that helps
