maybe..

=INDEX(A:A,50+50)



You will need to translate to your language...

this will pull the value from A100 into cell C1. You can change the 50+50 as needed.

Ok thank you,

another question: I have a number in C10 and another numberin C16. In cell H10 I want to obtain the value of C16 and I tried to write this: "=indice(D,=rif.riga(d10)+6)" but it doesn't work. why?

Thank you

Hi, rephrase my problem in another way. I need a function that given some numbers in column A returns only some of them. In others words I want to obtain in cells B1,B2,B3 etc the values of A10, A20, A30 etc respectively. That is, there is a distance of 10 between rows in column A.
how can I do this?

Thanks
