Script Quits Functioning, But Then Wont Function Again, Help!?

My script is supposed to work where, if the player gets under -$2, the script "quits functioning" (for lack of a better word). If the player goes below -$2, then back above it, the script quits working. My intentions are so that when below -$2 it quits, when above -$2, it starts functioning again. It doesn't and I don't know why, please help!

moneyToGive = -100
debounce = false
script.Parent.Touched:connect(function(hit)
	if debounce == true then return end
	player = game.Players:GetPlayerFromCharacter(hit.Parent)
	if player == nil then return end
	stat = player:findFirstChild("leaderstats")
	if stat == nil then return end
	cash = stat:findFirstChild("Cash")
	if cash == nil then return end
	debounce = true
	if cash.Value <= -2 then
		script.Sound2:Play()
	end
	if cash.Value >= -1 then
		cash.Value = cash.Value + moneyToGive
		game.Workspace.Tug.Body.Concrete.Transparency = 0
		game.Workspace.Tug.Body.Straps.Transparency = 0
		script.Sound:Play()
		game.Workspace.Tug.Body.Cash100l.BillboardGui.Enabled = true
		wait(3.5)
		game.Workspace.Tug.Body.Cash100l.BillboardGui.Enabled = false
		wait(2)
		debounce = false
	end
end)
