Why are my slash commands not working?

[vadindot]

I've been working on the following mod for use in Warsong. The functions themselves work fine if I use "/script". Also, if I paste this code into LuaSlinger the slash commands will work, but only if I load the script TWICE. Can anyone see what my mistake is?

function EBS_OnLoad()
	SLASH_IncTun1 = "/inct";
	SlashCmdList["IncTun"] = EBS_Incoming_Tunnel;
	SLASH_IncRoof1 = "/incr";
	SlashCmdList["IncRoof"] = EBS_Incoming_Roof;
	SLASH_IncLed1 = "/incl";
	SlashCmdList["IncLed"] = EBS_Incoming_Ledge;
	SLASH_IncRamp1 = "/incp";
	SlashCmdList["IncRamp"] = EBS_Incoming_Ramp;
end


function EBS_Incoming_Tunnel()
     SendChatMessage("INCOMING TUNNEL", "RAID");
end

function EBS_Incoming_Roof()
     SendChatMessage("INCOMING they are on our ROOF", "RAID");
end

function EBS_Incoming_Ledge()
     SendChatMessage("INCOMING SECOND FLOOR/ Ledge above Flag Room", "RAID");
end

function EBS_Incoming_Ramp()
     SendChatMessage("INCOMING coming up RAMP", "RAID");
end
