Question about mouseover macros for sch

[Darkoon]

This is my most frequently used macro for heals on either WHM or SCH:

/micon "Spell Name"
/ac "Spell Name" <mo>
/ac "Spell Name" <t>
/ac "Spell Name" <me>

I am using the exact Macro as you are, but I get an error message everytime. Do you know of a way to disable the error message?
