Ahh good spot!
In the spirit of the game, we don’t read other solutions before our attempt.
Thanks for letting us know, a quick regex patch did the trick

It’s interesting that most of the solutions I’ve seen to this involve using Repeating Groups…
My solution to this involved a recursive workflow (again): Bubble-challenges-solutions | Bubble Editor
But, of course, Repeating Groups (as well as a list: formatted as text) are both examples of built-in iterative processes in Bubble, and can both be used for preforming certain operations on lists (not just for displaying lists, as many people might think)… although not without certain limitations, especially relating to being able to extract data that’s been operated on from inside the RG or formatted text…
In fact… that gives me a great idea for the next challenge…
