Hi

In general
=IF(ISERROR(HLOOKUP(...)),ResponseWhenError,HLOOKU P(...))
or
IF(ISNA(HLOOKUP(...)),ResponseWhenNA,HLOOKUP(...))

Thanks Bernard - that works fine. I sometimes need to sum up values from
a
hlookup table and again get zeros with blank cells.

ie -

=SUM(HLOOKUP(BB$3,North_Water_SC,$B19,FALSE))+(HLO OKUP(BB$3,North_Waste_SC,$
L15,FALSE))+(HLOOKUP(BB$3,North_Long_Cycle,$V9,FAL SE))

Have you any ideas for this? Thanks for your help, Marianne

Try =IF(COUNT(B6:E6),SUM(B6:E6),"")
This is NOT an array formula

Hi, I'm trying to put a simple formula in excel to add up some cells -
the
trouble is when the cells are blank, excel still calculates it as a
zero.
I
know I can use the following to ignore the blanks
-=IF(SUM(B6:E6)=0,"",SUM(B6:E6))- but sometimes cells B6 to E6 might
contain
true zero scores. I've also tried using
if(isblank(sum(B6:E6)),"",(SUM(B6:E6))) but again it still returns
zero.
You'd think it would be something simple but I can't see it and it's
driving
me mad!!!!

Can anyone out there help????
