Hi all,
I have a problem to make validation to prevent duplication value in column.
Suppose I have arrays of data in column A (Employee ID) that contains
values, i want to no duplication value when i entering new data. If i
entered the same value as previous row then error message should be alert.
Any body can help what should the formula function applied. Thanks in
advance.
cheers.
