David, An aside, When it comes to numbers or a list of numbers it is safe to use space to delimit them because numbers do not typically contain spaces like tiddler titles may, EXCEPT IN YOUR EXAMPLE WHERE NUMBERS ARE EXPRESSED IN WORDS.
What I was think was to use a method such as split[ ] to separate each of the numbers/titles into a non deduplicated list, by then save them in a data tiddler where the value can be "repeated" but the index is always unique. So a set of numbers such as "1 2 3 1 2" can be saved in a data tiddler as; item1: 1 item2: 2 item3: 3 item4: 1 item5: 2 They will now not be deduped, each number is effectively unique as it is referenced by the unique item key. There is also the "select" keyword now on the setWidget that allows you to address the nth item, and you can use the range operator to "iterate" the nth number. In your example you are using titles for numbers is that correct? <$set name="HasDuplicates" value="one two two three [[twenty one]] [[twenty one]] [[forty six]]"> <$list filter="[subfilter<HasDuplicates>]"> </$list> item1: one item2: two item3: two item4: three item5: twenty one item6: twenty one item7: forty six I hope that is clearer.
