How would I make this script Filtering Enabled?

So I'm using this script to display a players name and rank in the group above their head. I currently have the script inserted in the StarterGUI folder. The name and rank is displayed above the player, but only on their screen. They cannot see anyone else's name or rank above that players head. I feel like this is due to Filtering Enabled, therefore I would like to know how to make this Filtering Enabled so that everyone can see the Name and Rank above the other players heads.

function checkTeam(player1)
local    team = nil
local    tc = nil
    for o,b in pairs(game.Teams:GetChildren()) do
        if b.TeamColor == player1.TeamColor then
            tc = b.Name
        end
    end
    for i,v in pairs(teams) do
        if v == tc then
            team = i
        end
    end
    local group = ids[team]
    return group
end

local player = game.Players.LocalPlayer
function assessRank()
if game.Players.LocalPlayer:IsInGroup(3087596) or not game:FindFirstChild("NetworkServer") then
    repeat wait() until game.Workspace:FindFirstChild(player.Name)
    repeat wait() until player.Character:FindFirstChild("Head")
    if player.Character:FindFirstChild("Rank") then
        player.Character.Rank:remove()
    end
local a = script.Rank:clone()
a.Parent = player.Character
a.Adornee = player.Character.Head
a.Frame.TextLabel.Text = player:GetRoleInGroup(3087596)
a.Frame.Name1.Text = player.Name
a.Frame.Name1.TextColor = player.TeamColor
if a.Frame.TextLabel.Text == "TGAR" then
    a.Frame.TextLabel.Text = "TGAR"
end
if player.TeamColor == BrickColor.new("Institutional white") or player.TeamColor == BrickColor.new("White") then
    a.Frame.Name1.TextStrokeTransparency = 1
end
if checkTeam(player) then
a.Frame.TextLabel.Text = player:GetRoleInGroup(checkTeam(player))
end
for c,b in pairs(terrorists) do
    if player:IsInGroup(0) then
        a.Frame.TextLabel.Text = "Hostiles"
        return
    end
end
repeat wait() until player.Character:FindFirstChild("Humanoid")
player.Character.Humanoid.NameOcclusion = "OccludeAll"
if player.Character:FindFirstChild("Body Colors") then
    player.Character["Body Colors"]:remove()
end
end
end

assessRank()

game.Players.LocalPlayer.Changed:connect(function (prop)
    if prop == "TeamColor" then
        assessRank()
    end
end)
