help with MOD()

[Nastech]

hi, not sure if need use of MOD, or INDEX / OFFSET..
I have 10 double columns of data, but only need the 1st col to figure into a
portion of a formula. (specifically, FE - FX), have a fixed cell where
designating number of columns to offset: $C$2

not sure how to apply, but think MOD is needed?
thanks

thank you.. think if post too much not get help.. tough question, but found
some examples "if" related. I used what would be correct column letters.

=SUM(--(MOD(COLUMN($FE9:$FX9),2)>MOD(COLUMN($FE9),2)),$FE9:$FX9)

=SUMPRODUCT(--(MOD(COLUMN($FE9:$FX9),2)=MOD(COLUMN($FX9),2)),$FE9:$AJ9,$FF9:$FW9)


My formula I am trying to make i think is what (will throw off?),
but 2nd portion of formula have figured out, 1st portion X: trying to grab
data from 'LO' / hi columns that are stored in a different section of
columns, follows:

=IF(E9=0,"",IF($C$2<2,$EC9/$EF9%-100,
X (everyother col by $C$2: FE FG FI FK..) /OFFSET(EF9,0,$C$2-1)%-100)

p.s.: formula calculates lowest low, (from lo-hi range) compared to a set
point (previous days balance).

correction: mis labeled one item:

=SUMPRODUCT(--(MOD(COLUMN($FE9:$FX38),2)=MOD(COLUMN($FX9),2)),$FE9:$FX9,$FF9:$FW9)

I need to externally designate how many columns offset, the following is an
example using for columns that are next to each other, that works for fixed
cell of $DM$6 (what working on needs cell: $C$2) thanks:

=IF(J9=0,"",SUMPRODUCT(EF9:INDEX(EF9:EX9,1,$DM$6)/EG9:INDEX(EG9:EY9,1,$DM$6)%-100))

maybe a: SUMPRODUCT(INDEX(MOD( ??

Hi,

I think you need to post some sample data and a description of what your
trying to do.

sorry, see 2nd error in item I was describing, if using this as an example:

=SUMPRODUCT(--(MOD(COLUMN($FE9:$FX9),2)=MOD(COLUMN($FX9),2)),$FE9:$AJ9,$FF9:$FW9)

should say: (AJ should be FX, ($FX9),2 should be ($FE9,2

=SUMPRODUCT(--(MOD(COLUMN($FE9:$FX9),2)=MOD(COLUMN($FE9),2)),$FE9:$FX9,$FF9:$FW9)
