How to make a "graphics" slider?

I am currently making a game which feature my own graphics slider to remove crumbs (bushes, flowers, and tall grass) and loose bricks, wood, or dirt from the map.

Here is the code I am using. (I made it myself, and I am an amateur at scripting GUIs.) And I haven't made the GUI yet, either, as I am not good at make sliding GUIs. Perhaps a number GUI would work. From a value of 0-1.

And the crumbs and debris are put into different players. So if one has his or her graphics settings down, then everyone who has their's up can still see the extra detail or vice versa.

local crumbs = game.Workspace.Players.ObjCrumbs
local debris = game.Workspace.Players.ObjDebris

if findFirstChild("GraphicsSlider")
	then
	if GraphicsSlider.Value = 0
		then
		findFirstChild.game.Worksapce.Players.crumbs
		crumbs(Destroy) else
		crumbs(Keep)
		
		if GraphicsSlider.Value = 0
			then
			findFirstChild.game.Workspace.Players.crumbs
			crumbs(Destroy) else
			crumbs(Keep)
		end
	end
end

Try a "click" function on a gui arrow so people can browse, then use the Tween function to move it across the screen, example below

    GUIOrFunction:TweenPosition(UDim2.new(0, 100,0, 300), "Out", "Quad")

Now that's just an example, you'll have to mess around with it to find out how you like it.
