How do I pass shipping units to Mal's cart?

I'm sure it's in the documentation somewhere, but I can't find it. How do I pass the shipping units to Mal's? I want to use a 3rd party shipping calculator, but my units aren't going to Mal's cart, so the calculator doesn't have anything to work with.

Question about View Cart Settings

I can't find any explaination about the following settings and the values to put in the text boxes:
From the Settings - Mal's e-commerce Shopping Cart Setup
View Cart Settings
• sd = your own session data
• shipping = a total shipping value (a response from an external shipping calculator)
• shipopts = description of shipping options chosen and to be stored
I am trying to set up a UPS shipping calculator on Mal's ecommerce.

Dear Robert:

Setting up your Shipping options is mainly a function of the Shopping Cart itself and not the XLEcom program. You do however have some shipping options via the program. The Database field labeled "Shipping Units" is defined as follows:

Shipping Units if using Mal's e-commerce (Optional)
This Unit value is only used for Mal's e-commerce. It can be a weight or other value for calculating shipping (default = 0). Enter numerical values only without the unit descriptor. Leaving a value in place does not affect any Paypal settings.

Since other users may have a similar inquiry, I created the following forum topic: Mal's Shopping Cart Shipping Options. This information was taken directly from Mal's website Support Section.

There are also some View Cart shipping settings within your Mal's e-commerce Shopping Cart Setup within the program as shown in the screen shot below:
