Thank you. It did work! Can you explain why the ISNUMBER and SEARC
made the difference?
SUMPRODUCT doesn't accept wildcards. ISNUMBER/SEARCH is a way o
achieving the same result. Let's assume that E1:I2 contains th
following data...
Code
-------------------
To_be_discussed x y To_be_discussed z
Yes No No Yes Ye
-------------------
...and that we have the following formula...
Code
-------------------
=SUMPRODUCT(ISNUMBER(SEARCH("Discussed",E1:I1))*(E2:I2="Yes")
-------------------
SEARCH("Discussed",E1:I1) returns the following array of values...
Code
-------------------
{7,#VALUE!,#VALUE!,7,#VALUE!}
Note that SEARCH returns a #VALUE! error when the text being searched is not found
-------------------
(ISNUMBER(SEARCH("Discussed",E1:AS1))) returns the following array o
values...
Code
-------------------
{TRUE,FALSE,FALSE,TRUE,FALSE
-------------------
(E2:AS2="Yes") returns the following array of values...
Code
-------------------
{TRUE,FALSE,FALSE,TRUE,TRUE
-------------------
SUMPRODUCT then multiplies the two arrays...
Code
-------------------
(ISNUMBER(SEARCH("Discussed",E1:I1))*(E2:I2="Yes"
-------------------
...and returns the folloiwng...
Code
-------------------
{1,0,0,1,0
-------------------
...which is summed, and returns 2. Note that numerical equivalent o
TRUE and FALSE is 1 and 0, respectively.
Hope this helps
