Hello,
I posted this on another group, but I don't seem to get a satisfactory
answer.
In an excel 2007 table (yes, a table), I want that one column has
unique values. I
want to check this at input time, with a data validation function.
Say that I have Table1
a b
qw 1
as 2
zx 3
fg 4
where a and b are column names (headers). I don't want another "qw" or
"zx"
value in column a.
I have tried with Data/Data Validation, with a formula like
=(countif([a];[a])=1)
but the countif function does not seem to recognaize structured
references in data validation formulas.
How could I get around this problem?
Thank you
