Please help with this formula

[Guest]

I have a spreadsheet; 25 participants for 31 days
each participant must log a catagory (eg PC) the spread sheet count the
number of PCs for the 31 days (eg. formula (=COUNTIF(E10:AI34,"PC")).
Question how can I calculate how many participates have logged a catagory PC
within the 31 days.

Hi C,

One way, Put =COUNTIF(E10:AI10,"PC") in cell AJ10
And drag down to AJ34

Then in another cell of your choice put
=COUNTIF(AJ10:AJ34,">0")

you could also try:
=SUM(--(MMULT((--(E10:AI34="PC")),TRANSPOSE(COLUMN(E10:AI10)/COLUMN(E10:AI10)))>0))
