Why does my script work solo, but not with multiple people?

local frame = script.Parent
local httpService = game:GetService('HttpService')
local template = script.Parent:WaitForChild('Template')
local tableOfPlayers = game.ReplicatedStorage.Values.TableOfPlayers
local decoded = httpService:JSONDecode(tableOfPlayers.Value)
local inRound = game.ReplicatedStorage.Values.InRound


local function checkForTable(table_, value)
    for i, v in pairs(table_) do
        if v == value then
            return true
        else
            return false
        end
    end
end

inRound.Changed:Connect(function()
    if inRound.Value == false then
        script.Parent.Visible = false
    else
        script.Parent.Visible = true
    end
end)

local cor = coroutine.create(function()
    while true do
        for i, plr in pairs(game.Players:GetPlayers()) do
            if checkForTable(decoded, plr.Name) and plr.ListedOnHealth.Value == false then
                local newTemp = template:Clone()
                newTemp.Name = plr.Name
                newTemp.Visible = true
                newTemp.Parent = table
            elseif not checkForTable(decoded, plr.Name) and plr.ListedOnHealth == true then
                local frame = script.Parent:FindFirstChild(plr.Name)
                frame:Destroy()
            end
        end
        print(decoded)
        wait(0.01)
    end
end)
coroutine.resume(cor)

I can't find the problem. Any help would be appreciated. this is a local script
