Excellent article!
I have a question.
How would delete blanks from start and end to avoid duplicates(caused by spaces) in function ConcatUniq?
Thank you very much!

I was successfully using the VBA function but something has gone wrong with it - I am only having a #VALUE! error returned now in places where it was working previously. I have combed my data for errors and tried removing and re-creating the VBA module, and renaming the function, nothing seems to be working. Any help would be appreciated, thanks!
