Countif after filterlist Excel - excel

Question

I would like to see a working example of how to get this formula properly working
=SUMPRODUCT(SUBTOTAL(3,OFFSET($P$7,ROW($P$8:$P$5500)-ROW($P$7),,1)),--($P$7:$P$5500="74"))
What im trying to achieve is count all the cells within a range that value is greater than
zero, but i need to get that working after i apply a filter. I have seen several examples and havent get it working, with the subtotal fx.
Thanks in advance, for any help!

Answer 1

Working example:
O P
4
5 6
6
7 Filter Data
8 1 74
9 0 74
10 1 74
11 0 74
12 1 74
13 0 74
Formula in P5:
=SUMPRODUCT(SUBTOTAL(103,OFFSET($P$7,ROW($P$8:$P$20)-ROW($P$7),,1)),--($P$8:$P$20=74))
Now you can filter column O and P5 counts only the visible 74.
With function 103 in SUBTOTAL, I really count only the visible cells. This means, also the manually hidden cells are not counted. With function 3 only the out filtered cells are not counted. If cells are manually hidden, they are counted, even if they are not visible.
And I have used the value 74 instead of the text "74". So in my example the column P contains numbers, not text.
How it works:
The formulas within SUMPRODUCT are in array (matrix) context. This means they are handled as if they are used in array formulas.
In array context {ROW($P$8:$P$20)-ROW($P$7)} gets ROW($P$8)-ROW($P$7) = 1, ROW($P$9)-ROW($P$7) = 2, ROW($P$10)-ROW($P$7) = 3 and so on.
OFFSET($P$7,1,,1) will get $P$7+1Row = $P$8, OFFSET($P$7,2,,1) will get $P$7+2Row = $P$9 and so on.
So {OFFSET($P$7,ROW($P$8:$P$20)-ROW($P$7),,1)} gets {$P$8,$P$9,$P$10,...}
Within SUBTOTAL(103, {$P$8,$P$9,$P$10,...}) it counts 1 if {$P$8,$P$9,$P$10,...} is visible and 0 if not.
So the SUMPRODUCT results in
SUMPRODUCT({1,0,1,0,1,0,0,...}, --($P$8:$P$20=74))
The {($P$8:$P$20=74)} results in {TRUE,TRUE,TRUE,FALSE,TRUE,...} depend of if $P$8:$P$20=74. The -- (*-1*-1) gets this in numeric context, so that the TRUE = 1 and FALSE = 0.
So the SUMPRODUCT finally results in
SUMPRODUCT({1,0,1,0,1,0,0,...}, {1,1,1,1,1,1,0,...})
