What program are you using for your click healing. Is it healbot as in the guide, or clique/vuhdo? If it is healbot then I can't really help you, but my initial thought was that if it is working fine ooc then it is probably set up fine. I know that with clique and vuhdo I can select different spells to be cast depending on whether the toon is in or out of combat. If this is not the case with healbot, then I am of no help to you sorry.

Cheers
