While Loop Using and Doesn't Start Looping?

local RepStorage = game:GetService("ReplicatedStorage");
local TimerValues = RepStorage:WaitForChild("Timer");
local min = TimerValues:WaitForChild("Min");
local sec = TimerValues:WaitForChild("Sec");
local StateOfGame = game:GetService("ServerStorage"):WaitForChild("StateOfGame");

function start_timer(minutes, seconds)
    min.Value = minutes;
    sec.Value = seconds;

    --For debugging
    print(min.Value);
    print(sec.Value);

    while min.Value == 0 and sec.Value == 0 do
        --blah blah blah
    end
end

while (true) do
    wait(5);
    if StateOfGame.Value == "Intermission" then
        start_timer(0, 30);

        repeat
            --print(tostring(min.Value).." and "..tostring(sec.Value));
            wait();
        until min.Value == 0 and sec.Value == 0;

        StateOfGame.Value = "Start";

    end
    wait()
end

When debugging and going line-by-line, it doesn't go into the loop even though min.Value == 0 and sec.Value == 30, what am I doing wrong?

This is a server script inside of ServerScriptService
