Another idea would probably be to first enter the first formula on the seventh row, then the following formulas could check if the seventh cell above is a formula¬Ö For instance, the first formula in C7, than in C8: =if(isformula(C1);average(B2:B8);"") That cell could then be copied down as far as needed.

Er, not really! Yes: that will work fine up to a point, displaying nothing in C8 to C13 and the required value in C14. But from C15 onwards, the formula is always referring back to a cell which *does* contain a formula, albeit one which displays nothing in the cell. From C14 onwards, the formula is identical to =AVERAGE(Bx:By) .

But you could do something very similar with C8 having:
=IF(C1<>"";AVERAGE(B2:B8);"") .
