This is an example of my leveling system and it says fired to much i want it to fire as much as neccesary so that i can stack them

local val = Instance.new("NumberValue")
val.Value = 0
val.Parent = workspace
local function onChange()
	if val.Value >= 15 then
		val.Value -= 15
		print("Changed")
	end
end

val:GetPropertyChangedSignal("Value"):Connect(onChange)

val.Value = 999

Your value is getting ran 6 times because Because the Value is changing in the function “-=” and that value is getting changed so it keeps Making that loop

#3

I wish to achieve that so it can stack them

#4

You can just use 2 NumberValues, one to connect the value changed signal to, and the other to store the actual value

#5 
local numberValue = Instance.new("NumberValue")
numberValue.Changed:Connect(function(value)
	print("Changed", value)
end)
numberValue.Parent = workspace

local value = 999
value -= math.floor(value / 15) * 15 -- this is the same as doing (while value >= 15 do value -= 15 end)
numberValue.Value = value

-- if you want to know how many times 15 was deducted from 999
print("Changed", math.floor(value / 15) , "Times")
#6 
local val = Instance.new("NumberValue")
val.Parent = workspace
val.Value = 0

local function onChange()
	local Connection
	Connection = val:GetPropertyChangedSignal("Value"):Connect(function()
		Connection:Disconnect()
		if val.Value >= 15 then
			val.Value -= 15
			print("Changed")
		end
		onChange()
	end)
end
onChange()
