Hey Guys

I hope you are well


I would need a code to find the first available cell in row 1

(in this case D1)

then put a formula in that cell ( in this case D1) and autofill it (fill the formula down).

tha autofill would be based in column C ( so the formula would stop in D3)

the formula could be the addition of A,B,C ( 1+2+3 In row 1 for example)


many thanks ! Antonio

A B C D
1 2 3
1 4 6
3 7 5
