The one I have works just fine. I do see something different with yours and let me try and explain this since I am a noob at all this coding
Line 54:
Lua Code:
local RefluxArg = string.format("%s %s", "switch", DeeUi-DPS)
This is different than mine. Mine reads like this.
Lua Code:
local RefluxArg = string.format("%s %s", "switch", NewProfile)
Now I think the reason your might not be working is this local thing that is making NewProfile like on line 53:
Lua Code:
local NewProfile = UseClassProfiles and ClassProfiles[class] or TankName
So change DeeUi-DPS to NewProfile and see if that works
