Ok! what I need to get, will be the the total mark in column H for every row,
you add eather 5 rows or 6 at column H, like for row 1=7.7, 2=7.30,etc....,
now what I wanna do it's to have this formula into a funtion in a add in
file, so I can use it on diferent workbooks that I used daily so I can save
space in my hard drive by save in only what the data I need . thx.

So far, it seems to me that in your form,ula, it doesn't matter what G1 is
since it always returns:
+ (SUM(A2:A7)+J1)/I1) when J1 is 7, and
+ (SUM(A2:A6)+J1)/I1) when J1 is not 7

The formula can therefore be replaced by:
= ( SUM(A2:A6) + (J1=7)*A7 + J1 ) / I1
explanation of (J1=7)*A7
+ if J1=7 then (J1=7) is True therefore True*A7 = A7. So A7 is added.
+ if J1<7 then (J1=7) is False therefore False*A7 = 0. So A7 is not added.

+ Why don't you give an example of the formula on a few rows.
+ When in row 1 , the formula is SUM(A2:A6) + (J1=7)*A7 + J1 ) / I1
What do you want these range to be when the formula is in row 2 ?

what I'm trying to do, it's something like this
:=IF(G10,(IF(J1=7,((SUM(A2:A6)+J1)/I1))),(IF(J1=7,(SUM(A2:A7)/I1),(SUM(A2:A6)I1)))).
where G=F-H,for each row.
