Hi there,
I am wondering how to count the number of unique values inside an array.
For example, there is an array named country and it containes 3 country names, where Germany is doubled. So I would like to know that there are 2 unique country names in the array.
Has anybody an idea how to achive that?
Thanx for any help on that,
Merlin
