Macro for Battleground Defence

[Jynks]

/run SendChatMessage(string.format("{Triangle} %s {Triangle} - CLEAR",GetMinimapZoneText()),select(2,GetInstanceInfo())=="pvp" and "BATTLEGROUND" or GetNumWorldStateUI()>0 and "RAID" or "YELL")

I used to have a bunch of BG macros for yelling "Incoming" "Clear" and "HELP"... but I started a new toon to level in BGs this time and they no longer work.. can anyone help me?

The macro is supposed to automatically call out the BG location I am standing in when I press it.
