Hi Ketho,

now it works thanks to your input and tips.

I have tried also with unitid in my past tries but I use in a wrongly way.

I used:

guid = UnitGUID("unit")

and then that value in the function to calculate the score.
But it doesn't work.

Now following your suggest I change the code in this way and it works nicely:

if event == "UPDATE_MOUSEOVER_UNIT" then 
        if (UnitIsPlayer("mouseover")) then
            local score = C_PlayerInfo.GetPlayerMythicPlusRatingSummary("mouseover").currentSeasonScore
            local r, g, b = C_ChallengeMode.GetDungeonScoreRarityColor(C_PlayerInfo.GetPlayerMythicPlusRatingSummary("mouseover").currentSeasonScore):GetRGB()
            GameTooltip:AddLine(" ")
            GameTooltip:AddDoubleLine("Mythic+ score",score,1,1,0,r,g,b)        
            GameTooltip:Show()
        end
    end

Don't know why it didn't work in other way :/
But now it works and I am happy




Thanks so much for you tips.
