Hi Dr Matt

Just came here from Matt Parker's YouTube post of 28th Aug re the Partridge problem. I tried - and failed at the first click - your interactive model / puzzle "squares" when trying to drag a square resulted in the "blocked" icon to say "Naah, you're trying to do something illegal". I saw something that indicated it's written in JavaScript - I do have JavaScript set as "allowed" by default so that's evidently not the problem...

@Chris B: I put a little more text on the interactive page. Hopefully it's a bit clearer now what it's expecting (click and click, not drag)

@Chris B: Oh never mind ???? I just went back there and found the correct way to move the squares. Duh, sorry!
