question about grid enhanced & incoming heals on my Priest

[rotten]

I have my grid enhanced/classic mouseover set up pretty well, all things considered...but I can't seem to figure out how to get the incoming heal amount to show up in the foreground/player's HP defecit. I believe that grid supported that in vanilla. I can't even get a lower corner to light up when an incoming heal is in progress. Any and all help with this will be greatly appreciated!

At least my grid version does not support this.
