How do I make my I, v in pairs work properly?

I'm currently attempting to create a part when you touch it, it spawns in a model from a folder within workspace. I've got most of it down, although my issue is the value of " i, v " not changing after the script runs...

Here is the code...

local used = false

local stage = script.Parent

function OnTouched(part)
    local ObbyTable =  game.Workspace.stages:GetChildren()
    for i, v in pairs(ObbyTable) do
        if used == false then
	    local newstage = v:Clone()
	    newstage.Parent = workspace.newstages
	    newstage.PrimaryPart = newstage.Main
	    newstage:SetPrimaryPartCFrame(newstage:GetPrimaryPartCFrame() * CFrame.new(0,0,-34))
	    print(i, v)
	    used = true 
        end
    end
end

script.Parent.Touched:connect(OnTouched)

'i' will be 1 because it runs only 1 times. And 'v' will not change because you just clone. Clone doesn't destroy or move.
