Spell Lock Macro

[alepoo]

Hi, was wondering if anybody could help me fix this macro. For some reason it doesn't work. It's taken from the wowwiki site.

"When used, this macro will focus your current target (if you don't already have a focus) and cast Spell Lock on that target. If shift is held down while using this macro it will focus your current target and cast Spell Lock on that target (changing focus), if you don't have a target it will simply clear your focus. If ctrl is held down while using this macro it will simply Spell Lock the target your mouse is hovering (this way you won't lose your current target)."

#showtooltip Spell Lock
/clearfocus [modifier:shift]
/focus [target=focus, noexists]
/cast [nomodifer, pet:Felhunter, target=focus, harm] Spell Lock; [modifier:ctrl, pet:Felhunter, target=mouseover, harm] Spell Lock

I don't know how to fix it, but this looks like a handy one, a bump to you and I hope someone knows how :P
