Looking to Modify Aura/Tint Healthcolor script

I would like to turn off the Aura aspect. I am mainly keeping this script for the blood squirt and healing animation only. I use Auras for other stuff. When I set Aura to 0 - it still shows the green aura around the character. If I set it blank or NaN - the script breaks. I just want the ability to turn the Aura off. Also I do not want to use TINT either - that just looks ugly.

!aura will give you a menu, set  Show PC Health and   Show NPC Health to No

show PC health - doesnt that prevent them from seeing the green bar above their heads too?

No it only changes the Aura on and off. The bars will stay.
