Hey. Im looking to count the number of times in a table where two cells in a row have certain properties, for example:

i want to know how many times column 4 has "High" written it when (and only when) column 6 has "Black" in it.

could this be done as a formula or would i have to use VBA? if the latter, could someone help me with the code to write - im just learning VBA.

thanks

chris

Move date out one month or year
Use =EDATE(A2,1) for one month later. Use EDATE(A2,12) for one year later.

Good afternoon geddiknight

Assuming that your column 4 is D and column 6 is F, then something like this should suffice :

=SUMPRODUCT(--(D1:D100="High"),--(F1:F100="Black"))

Hi VogII and DominicB.

I'm still trying to learn about sumproduct - can you explain please how this works, and what the -- do ?

I understand how basic sumproducts work, but not this one.

Cheers !

In addition to that, I'll show how it evaluates by showing it on the spreadsheet (on a smaller scale).

Columns I and J show the TRUE/FALSE values for each condition for Columns D and F. Columns K and L show the TRUE/FALSE values coerced to 1 and 0 respectively. Each row is multiplied so 1x1=1 but if either condition is FALSE it will return 0 as anything multiplied by 0 is 0. These are all then summed giving you the count.
