    elseif not UnitAffectingCombat("player") then
        RaidNotice_AddMessage(RaidWarningFrame, sender .." HAS ENTERED COMBAT", ChatTypeInfo["RAID_WARNING"])			
    end    
end

is there a way to declare the variables one further level in?

for example I know you can do

Code:

local _,target = strsplit(" ", msg, 2)

and declare it right in the operation you're doing. just that quick question,

thanks

You don't need to declare those variables as local at all, because they are automatically defined as local to the scope of the loop when used in a "for" statement:

Code:

for k, v in pairs(t) do
   -- k and v exist here
end
-- but not here

Code:

for i = 1, 10 do
   -- i exists here
end
-- but not here
