Random Player Chooser Then Saying The Name Script Not Working :/?

You're trying to do concatenation, which uses .. to combine two strings, and not a comma.

You're also using a ton of lines instead of a for loop to change the text.

The whole script is in a loop for no reason. The loop has an infinite loop inside of it, so it's never going to repeat.

You're probably going to have an issue with that script.Disabled = true line later on if you don't get rid of it.

You wrote "text" instead of "Text" a couple times.

There's another issue with your choosing random players; the second one might be the same as the first one. Using table.remove on the list of players fixes that.

You're using a ScreenGui inside of workspace. It looks like what you're trying to display this text to everyone in the game, but ScreenGuis don't display anywhere other than the PlayerGui, so you might want to use a Hint (deprecated) instead, or set up a client-side text display that receives signals from a RemoteEvent.

local t = workspace.ScreenGui.TextBox
while wait(1) do
	if t.Text == "Enough Players Needed To Play!" then
		workspace.NeedOneMorePlayers.Disabled = true
		workspace.NeedTwoMorePlayers.Disabled = true
		workspace.NeedThreeMorePlayers.Disabled = true
		workspace.NeedZeroMorePlayers.Disabled = true
		t.Text = "Game Starting Soon..."
		wait(6)
		for i = 17, 1, -1 do
			t.Text = "Intermission ("..i..")"
			wait(1)
		end
		t.Text = "Starting Game..."
		-- script.Disabled = true
		local plrs = game.Players:GetPlayers()
		local select = table.remove(plrs,math.random(#plrs))
		t.Text = "The First Seeker Will Be "..select.Name
		wait(6)
		local plrs = game.Players:GetPlayers()
		local select2 = table.remove(plrs,math.random(#plrs))
		t.Text = "The Second Seeker Will Be "..select2.Name
		wait(6)
		t.Text = "The Map Chosen Is..."
	end
end
