ive just tryied it further down the sheet and it seems to work ok...using
this

=(SUMPRODUCT((MOD(COLUMN(G24:FA24),6)=1)*(G24:FA24 <=C24)*G24:FA24)+C24*SUMPRODUCT((MOD(COLUMN(G24:FA 24),6)=1)*(G24:FA24C24)+FJ24))*(C24*$E24)/(C24*52)

odd

The formula seems to work as you've described. Let's take a look at the
following example where...

D6 contains 100

H6 contains 180

N6 contains 60

T6 contains 160

Z6 contains 80

...shouldn't the answer be 340?

why is this not working? it should add up the values of every 6th cell
(H6
through to FB6), but if any cell is over the value of D6 then D6 's value
is
taken as the value for that particular cell in that particular instance.
it
seemed to be working, but if i enter a value of over D6 in H6 etc, the
answer is worng.

=SUMPRODUCT((MOD(COLUMN(H6:FB6),6)=2)*(H6:FB6<=D6) *H6:FB6)+D6*SUMPRODUCT((MOD(
COLUMN(H6:FB6),6)=2)*(H6:FB6D6))

cheers!
