WoWInterface - If Statement Trouble

So I have this if statement:

Code:

local isBuffed1,_,_,_,_,_,_,isMine1 = UnitAura("Player","Battle Shout");

local isBuffed2,_,_,_,_,_,_,isMine2 = UnitAura("Player","Commanding Shout");

if((isBuffed1 ~= nil and isBuffed2 ~= nil) or isMine1 == "PLAYER" or isMine2 == "PLAYER") then

        bString = bString.."\nTest :O"

else

        bString = bString.."\nShout"

end

It's only half working, and I guess I'm to dumb to notice why. :P

Basically, the problem is that the vars "isMine1" and "isMine2" are giving me trouble. If I go in game, cast a shout on myself, and then print the var it returns "PLAYER". However, in the if statement I can never get either one to return true for isMine1 == "PLAYER"

Anyone notice what I'm doing wrong, cause I'm stumped. =/
