My remoteevent isn't going through??

Server script

local sendTables = game.ReplicatedStorage.RemoteEvents.SendTables 
local module = require(game.ServerScriptService.module)

local players = {}
local non_players = {}

while true do
    for i, plr in pairs(game.Players:GetPlayers()) do
        if plr.TeamName.Value == 'Player' and plr.ListedOnHealth.Value == false then
            if module.checkForTable(non_players, plr.Name)  then
                table.remove(non_players, table.find(non_players, plr.Name))
            end
            table.insert(players, 1, plr.Name)
            plr.ListedOnHealth.Value = true
        elseif plr.TeamName.Value ~= 'Player' and plr.ListedOnHealth.Value == true then
            if module.checkForTable(players, plr.Name) then
                table.remove(players, table.find(players, plr.Name))
            end
            table.insert(non_players, 1, plr.Name)
        end
    end 
    print(players)
    print(non_players)
    sendTables:FireAllClients(players, non_players)
    wait(0.1)
end

Local Script

local frame = script.Parent.Frame
local template = frame.Template
local sendTables = game.ReplicatedStorage.RemoteEvents.SendTables




sendTables.OnClientEvent:Connect(function(plr, players, non_players)
    if players and non_players then
        for i, plr in pairs(players) do
            print('going thru')
            if script.Parent:FindFirstChild(plr.Name) == nil then
                local newTemp = template:Clone()
                newTemp.Name = plr.Name
                newTemp.Parent = frame
            end
        end
        for i, plr in pairs(non_players) do
            print('going thru2')
            if script.Parent:FindFirstChild(plr.Name) ~= nil then
                local destroyPlayer = script.Parent:FindFirstChild(plr.Name)
                destroyPlayer:Destroy()
            end
        end
    end
end)

I don't know what the problem is. If you do give an answer, please describe why. Thank you!
