Hi
I would like conditional formatting which colours every other different group yellow so that each group stands out.
The group in question is decided in column C, so as long as, say, C4 reads the same as C3, the background will be the same colour as the row above etc.
Now, I managed to do this conditional formatting by creating formulae in column A that returned either a 1, 2, or empty string depending on what was going on in column C, then the conditional formatting coloured the row yellow if the result of the formula in that row was 1.
(don't get what I mean? - here's the formula in column A):
=IF(ISBLANK(C3),"",IF(C3=C2,A2,IF(AND(C3<>C2,A2=1),2,IF(AND(C3<>C2,A2=2),1,""))))
Now I think I've overcomplicated things in this explanation here because what I actually want is conditional formatting to colour every second group yellow - even when an AutoFilter is switched on. So let's say I have groups 1, 2, and 3. Group 1 background is yellow, 2 is white, 3 is yellow and so on. But if a filter completely hides group 2, then I need group 1 to be yellow and group 3 to be white - so that it is obvious I'm looking at two groups.
OK, so I'm crap at explaining - can you help though?
