I got this on the forums awhile back. I am having some trouble with it in instances. It should command people to heal the focus target if the focus clicks on a party member and presses the macro. For some reason its not working when I instance. It seems to work fine out of combat. maybe one of the modifiers is off. Can a macro pro take a look at it and let me know which part is messed up?
