Hey Jussi,

If you want to find the duplicate values in an array... give this trick a
try

1) turn the array into a string
2) store it in a temp string variable
3) find the first occurence of the value you want
4) put the rest of the string in another temp variable
5) do a replace(tempString, "what you want to replace,", "")
6) concat the 2 temp strings together
7) split the string back into an array

If you notice in step 5 I included the coma in the string you want to
replace
and that's because we don't want any duplicate comas it'll screw up the
splitting process at the end

It's less cpu intensive than doing a for loop to find the duplicates
(At least I think so, correct me if I'm wrong)

I've used a similar technique to filter certain items from a string array
don't think this technique would work on other kinds of arrays

I hope it helps

Regards
Dimitris
