It keeps saying "Attempt to compare number with nil"? Can anyone help?

function checkSurvivorNumber(count)
    local count = 0
    local players = game.Players:GetChildren()
    for i = 1, #players do
        if players[i] ~= nil then
        if players[i].TeamColor == BrickColor.new("Bright blue") then
                count = count + 1
                print("Checking Survivors")

            end
       end
    end
end

if count < 1 or count == nil then
     time.Value = 0 
     for i = 1,#players do
             if players[i].TeamColor == BrickColor.new("Bright red") then
         game.Workspace.DebugOutput.Value = "Awarding Killer's points"
               end
            end
       game.Workspace.Killerwin.Value = true
       end
       print("Checking if killers won")

On Line 15, it keeps saying "Attempt to compare number with nil". I've tried everything and I'm still confused. I'm new to scripting and I just wanted to know why it caused this. Even if I delete COUNT == NIL it still says the same thing over and over.
