[Year 12 IPM] Excel problem -- How to..

[Colin C Consiglio]

Lets assume data is in Columns A and B, starting in Row 19.....and looks
like this
A	B	C
R	F	TRUE
R	F	TRUE
R		FALSE
R	F	TRUE

Column C uses the logical AND function in formula like this
=AND(A19="R",B19="F")

This causes column C celss to result in TRUE or FALSE

In another cell you can use the COUNTIF function to count the number of
TRUEs
e.g. =COUNTIF(C19:C22,TRUE)

Thanks for the opportunity to play and test the boundaries of Excel again..

Hi all,

I wish to count the number of entries that meet two conditions.
Eg: Count how many times "R" appears in column A in the same row  as "F"
appears in column B.

I have tried to use the logical function "and" in conjunction with "countif"
but can't seem to make it work.

Anyone have a solution?

Cheers
