I need help with a formula
A1 1
A2 yes
A3 3.00
A4 10
A5 20
A6 25
A7 22
A8 30
A9 2
A10 4
I need a formula in A11 that will do the following...
If A3>0 then A10=A3*(A4:A8)
If A3=0 and(or(A1=1,A2=yes) (A4:A8)*A9,(A4:A8)*A10

Thanks in advance
Steve
 
Hi Steve

You can't by formula or function use a formula in A11 that changes an
entry made in another cell; in your case A10.

It seems like you need a formula for A10 first and then a formula for
A11

If A3>0 then A10=A3*(A4:A8), should have been
If A3>0 then A11=A3*(A4:A8)
If A3=0 and(or(A1=1,A2=yes) (A4:A8)*A9,(A4:A8)*A10

Thanks!!!
 
Hi Steve!

Try:

=IF(A3<0,"",IF(A3=0,IF(OR(A1=1,A2="yes"),SUM(A4:A8)*A9,SUM(A4:A8*A10))
,A3*SUM(A4:A8)))

Check carefully with the various alternatives as there may have been a
misunderstanding of your statement.
I like to cover the whole number scale which is why I cover A4<0. But
that's a personal thing.

Thanks! that works. In modifying the formula to my use, is there any way to sum every 4th cell in a column other than b1+b5+b9...+bn ?
 
One quick? way:

If the data to be summed is in col B, B1 down

Put in C1: =MOD(ROW()-1,4)

Copy C1 down col C
as many rows as there is data in col B

(this sets up a repeating series: 0,1,2,3 down col C
which we can make use of as a criteria in SUMIF)

Now put in say, D1: =SUMIF(C:C,0,B:B)
(zero is used as the criteria in SUMIF
as we want b1+b5+b9+...)

D1 will return the sum of b1+b5+b9...+bn

Similarly

: =SUMIF(C:C,1,B:B)
will return the sum of b2+b6+b10...+bn

: =SUMIF(C:C,2,B:B)
will return the sum of b3+b7+b11...+bn

and so on.

Adapt to suit.
 
Hi Steve!

Here's a general purpose approach by Bob Philips that I found on a
Google Search:

=SUMPRODUCT((B1:B31)*(MOD(ROW(B1:B31)-ROW(B1),4)+1=1))

The general formula is:

=SUMPRODUCT((B1:B31)*(MOD(ROW(B1:B31)-ROW(B1),n)+m=1))
Where n is the spacing between rows to be added (in your case 4)
And m is where in the range you want to start (in your case 1)

Just to add-on a little more ..
Put in C1: =MOD(ROW()-1,4)
Click to expand...

Just change the number "4" inside : =MOD(ROW()-1,4)
to suit the criteria of every "nth" cell in the column, if the
criteria is other than every 4th cell in col B

Play around, it's fun !
 
So if I wanted to sum every 4th from B51:B111, would the following would be true
=SUMPRODUCT((B51:B111)*(MOD(ROW(B51:B111)-ROW(B51),4)+51=1)
Its not working for some reaso
Thanks
 
Hi Steve!

Use:

=SUMPRODUCT((B51:B111)*(MOD(ROW(B51:B111)-ROW(B51),4)+1=1))

Returns sum of every 4th entry from and including the first cell in
the range B51:B111
