Quantity Discount Add on - adding levels not working

In Quantity Discounts I downloaded today it works great. I am trying to add additional levels as discussed using the following code:

function setup() {
// Add extra levels and discounts here in this manner:
// "Buy more than 100 items, get 50 (% or $, as per admin) off"
$this->add_extra_level_discount(100, 50);
}

This is cut & paste from instructions but it does not seem to add the discount - anyone else experience this? thanks

Just tested in 1.5.0 - works fine for me. What are your settings in admin->modules->order total->Quantity Discounts?

Sorry for the delay:

If you want to give $55 off orders over $500, you'll need to use this function setup():

function setup() {
   $this->add_extra_level_discount(500, 55);
}

Your last level was 450 (with $50 off).
