the if thing.name == playerLST then are the same but isnt activating?

function Player()
    local ray = Ray.new(Root.Parent.Head.Position,(Root.Parent.Head.CFrame.LookVector).unit*5000)
    local hit, position = game.Workspace:FindPartOnRay(ray)
    local playerList = game.Players:GetChildren()
    if hit ~= nil then
        local Thing = hit.Parent
        if Thing:IsA("Accoutrement") ~= true then
            for i, v in pairs(playerList) do
                local playerLST = v
                print (playerLST)
                print (Thing.Name)
                if Thing.Name == playerLST.Name then
                    local distance = (hit.Position - Root.Parent.Head.Position).magnitude
                    print(distance)
                end
            end
        end
    end
end

You were trying to compare a String to an Object. The fix was simply to add a .Name after playerLST.
