Interaction Between Two Order Total Modules

[retched]

Is there a way to take the result of one order total module and apply its result to another?

For example:

I have two modules installed.

One module will give a discount based on how many items was ordered.

The second module will calculate tax on the order.

What is supposed to happen is the cart will calculate the discount the order total using module one. However, what is going is the module doing the discount will discount the order... but the tax module will still charge tax on the entire order.

Apparently your discount module isn't doing all that it needs to do.

I recommend studying how the existing discount modules work, and follow suit.
