Why do I get the error "'for' initial value must be a number" ?

Hey, I'm making a round script and I'm using a ModuleScript to store all of the settings. This is what it looks like:

local Settings = {}
	Intermission = 15;
	GameTime = 60;
		
		
		
		
		
return Settings

This script is inside the main game script. I created variables in the main script to access these values.

--[ Game Variables
Intermission = Settings.Intermission
GameTime = Settings.GameTime 

I did it for the actual script too ;P

--[ Modules
Settings = require(script.Settings)

And I used it for the intermission like this:

if game.Players.NumPlayers >= 1 then
		for i = Intermission, 0, -1 do
			ChangeText("Intermission: " .. i)
			wait(1)
		end

And I get this error

Workspace.CoreGame:46: 'for' initial value must be a number

If I remove the Intermission after for i = and replace it with an actual number it works fine. But I want to have it connect to the settings module script
