Sum Every Third Column In A Row with 68 Columns
 

Greetings,

I have a list of names in column A starting at row 55. I need to get
the sum of every third column starting in column F thru CR and place
it in column C. Then do the same thing starting in column G thru CS
and placing that sum into column D. And finally, sum column H thru CT
and place that figure in column E.

Any one have any idea what that formula would look like?

Any help would be greatly appreciated.

Hi

Try
=SUMPRODUCT((MOD(COLUMN(F55:CT55),3)=0)*(F55:CT55) )
=SUMPRODUCT((MOD(COLUMN(F55:CT55),3)=1)*(F55:CT55) )
=SUMPRODUCT((MOD(COLUMN(F55:CT55),3)=2)*(F55:CT55) )

Thank you Pao and Harold,

Poa:
Excellent solution, only needed to know which parameter needed to be
changed to effect all three.

Harold:
Thanks for the excellent solution and for supplying all three formulas
with the different parameters 0 - 2.

Again, a very big thank you.
