--declare variables
    local OnlineButton = script.Parent.Frame.OnlineButton
    local StoryButton = script.Parent.Frame.StoryButton
    local RandomModeButton = script.Parent.Frame.RandomModeButton
    local Console = script.Parent.Frame.Console
    local ChosenMode = "Unknown"
    local clearToLoad = true
    local randomMode = math.random(0,1)
-- variables for check  
    local check0 = true
    local check1 = false

-- initialize components
 function render()
    clearToLoad = true
    Console.TextScaled = true
    clear(Console)
    init()
end

function clear(text)
    text.Text = ""
end

 function loadGame()
    Console.Text = "No errors yet! :D"
    Console.Text = Console.Text .. '\nPlease wait at least 5 seconds for loading \nbefore clicking a button.'
    if (OnlineButton == script.Parent.Frame.OnlineButton) then
    elseif (check0 == false) then
        check0 = true
        check()

        wait(8.5)

function init()

--Now for the code and calling these functions
print 'start'
loadGame()
OnlineButton.MouseButton1Click:connect(PlayGame("online", true, false))
    StoryButton.MouseButton1Click:connect(PlayGame("story", true, false))
    RandomModeButton.MouseButton1Click:connect(PlayGame("random", true, true))

It would certainly help if you told us what line the error was on, indicated by the output. funyun 958 — 9y

Remember you can't call functions that were not previously declared. Put the clear function above the render function. funyun 958 — 9y

In the past, this unhelpful error (coupled with having no line number) indicated that you were passing nil to a :connect.

This definitely would happen on line 101, 102, 103:

You want to give :connect the name of a function, so that it knows how to call it repeatedly. When you give it the call of a function, all it knows is what the function returned (which is nothing).

You could define functions PlayOnline, PlayStory, PlayRandom instead. It almost looks like this would make more sense since your PlayGame just decides which set of things needs to be done.

Or, you can use an anonymous function that do this for you:

OnlineButton.MouseButton1Click:connect(function() PlayGame("online", true, false) end)
StoryButton.MouseButton1Click:connect(function() PlayGame("story", true, false) end)
RandomModeButton.MouseButton1Click:connect(function() PlayGame("random", true, true) end)
