button to gsay and cast

[scyllel]

I've been tweaking some existing mods to cast heals (not cures) on players in the group window. I can get most of the spells to fire off, but the one with a chat command is giving me grief. Does anybody see what my problem is? Am I even trying to approach this in the right way?

OnPress="target_none target_group_member 1 gsay=I'm stunned while I focus on healing %T. useability Focused Benefaction"

thanks,

Scyllel
