Leaderboard Player Rank gui help?

I'm trying to make a gui I made display the player's rank and i'm having trouble finding out how to do that, I already made the "Rank" stat on the leaderboard.(i'm using the default linkedleaderboard and I have a gui named "YourRank" with a Frame named "Frame" and a Text Label named "Rankz")

stands = {}
CTF_mode = false

    if stats ~= nil then
        local deaths = stats:findFirstChild("Wipeouts")
        deaths.Value = deaths.Value + 1

        -- do short dance to try and find the killer

        local killer = getKillerOfHumanoidIfStillInGame(humanoid)

        handleKillCount(humanoid, player)
    end
end

function onPlayerRespawn(property, player)
    -- need to connect to new humanoid

    if property == "Character" and player.Character ~= nil then
        local humanoid = player.Character.Humanoid
            local p = player
            local h = humanoid
            humanoid.Died:connect(function() onHumanoidDied(h, p) end )
    end
end

function getKillerOfHumanoidIfStillInGame(humanoid)
    -- returns the player object that killed this humanoid
    -- returns nil if the killer is no longer in the game

    -- check for kill tag on humanoid - may be more than one - todo: deal with this
    local tag = humanoid:findFirstChild("creator")

    -- find player with name on tag
    if tag ~= nil then

        local killer = tag.Value
        if killer.Parent ~= nil then -- killer still in game
