Aura/tint healthcolor hot appearing on all PC's tokens

As far as I can tell I've set them all up exactly the same but not all show their healthcolor. any idea what I've done wrong or may have done differently?

My guess is that some of your tokens are ‘PCs’ (controlled by a non-GM player) and some are ‘NPCs’ (not controlled by any non-GM players).  Aura/Tint Healthcolors can treat those two types of tokens differently. I believe you just need to look at the help menu which should be (I’m doing this from memory): !aura --help 

Thanks Jarren, I got it sorted out. There was an odd combination of errors. One of them being a number assigned to the max. The problem token I used to test a bunch of stuff kept loosing it's data element assignment too. So even when I found the max issue it still didn't work because by then the HP was gone. Once I got them all in correctly at the same time it started working. But I think the real culprit was having a number and not "max" And the fact that you can't type Max you have to delete it and let it fill in.
