Removing duplicate values in a text-field

[spr0cket5]

Hello there!

I've searched the forums but couldn't find any solution.

I have a text-field that contains a list of values. Like this for example:

1

2

2

3

3

4

Now I want to remove all duplicate values so that I get a list like this:

1

2

3

4

But I'm kind of lost right now, so any help -- even a little push into the right direction -- would be greatly appreciated.

Thanks,

Ralph

Well, found it. (I guess it was too late last night when I tried to make it all work.)

At www.briandunning.com there is a custom function to remove duplicates.

Exactly what I was looking for.
