It should start in A2 but the formula should affect whole range, i mean if i copy AVERAGE($A$2:INDEX($A$2:$A$12;C2)) to C5, C6, C7 etc.. it is still fixed on A2, and does not move down.. i mean the average is fixed on the 1st cell displaying average of previous values, but is not copied down does not displaying averages of followed cells.
I guess should i use two index function within average formula? So the average is counted at each followed cell in column C based on C2 value?
