I am using a macro like the one below so that I can save on hotbar space for those times when I scale down my level.

/macroicon Stone
/ac "Stone II"
/ac "Stone"


It does its job and casts Stone II when I am at level, and casts Stone I when I scale down below the required level.

My only gripe is that is causes an error message to pop up on the screen every time I use it (because of global cd). I am not referring to the chat window error messages, I mean the heads-up error messages.

My query is to whether or not there is a macro command to disable error messages for the current macro. I don't want to disable those error messages altogether (not even sure it's possible).
