I feel you're reading more into my words than is there. If you'd like me to be more clear

Yes, the point is that he's not sorting on the correct values (most likely) and he can certainly use a function to translate the keys within the sort block just as well as using a ST to precache the correctly translated keys.

Didn't talk at all about what's a function and what isn't one. My main point is and was only that his sort order was probably not what he wanted. The means of fixing it is up to him, I just provided a single example.

Nevertheless, thanks again for sharing alternative methods.

Cheers
