World of Warcraft - Macro - Place raid markers then clear

This macro is now broken, I was going to rework it but found an addon that has more usability with the added functionality of raid marking.

Maggz Marker 

This macro will place a world raid marker each click for 3 and then clear all the markers on the fourth click.

/run local b=ActionButton8 _WMH=_WMH or(b:SetAttribute("*type5","macro")or SecureHandlerWrapScript(b,"PreClick",b,'Z=(Z or 0)%4+3 self:SetAttribute("macrotext","/wm "..Z.."\\10/cwm "..Z)'))or 1
/click ActionButton8 Button5
