why are you using a cutom enrty?
You simply want someboy to choose a value form the list,
so set the datavalidation to LIST and in the source type

=valList

Hi all,

I have the following Data Validation as per a reply to
my
ptrev query

Step1:
Create a defined name for the list on sheet2
(for the example i made it a dynamic name, but it could
be fixed )
valList =OFFSET(IncomeData!$D$1,1,0,COUNTA(IncomeData!
D:D)-1)


Step2:
Define Validation on Sheet Income for Cell $c$7 as
custom:
=COUNTIF(valList;$D$7)=0

and I have error Message to say "That Number already
entered"

when I enter a number which already exists in my ValList
it gives me my custom error mesage with two buttons "OK"
and "CANCEL" and when I select Ok it accepts the number
and moves to the next cell instead of not accepting that
number ..???!!!!

what would be the possible cause?

TIA
Soniya
