Hi
I have this problem:

AF5 has the following formula
=IF(COUNT(Q5:AE5)=0,"-",SUMPRODUCT(--(MOD(COLUMN($P$3:$AD$3)-COLUMN($P$3),2)=0),$P$3:AD$3,Q5:AE5)*0.01)
Resulting in a % or "-"

BF5 has this formula
=IF(COUNT(AQ5:BE5)=0,"-",SUMPRODUCT(--(MOD(COLUMN($AP$3:$BD$3)-COLUMN($AP$3),2)=0),AP$3:$BD$3,AQ5:BE5)*0.01)

NOW...

BM5 needs to decide if AF5 & BF5 have % [may also be 0%] or "-" then if
either of these cells has a % value, I need to devide sum by 2, if not I want
to display "-".

I think I need a combination of IF, ISNUMBER and another operater but can't
get it to work.

Kind Regards
Tanya
