Zone rates & MZMT shipping modules not working properly?

[langtu123]

Hi,

I'm currently lost in trying get Dreamscape's MZMT & Zen Cart's Zone Rates Shipping Modules working properly.
No matter what I've done, the output (when customers check out) of MZMT look like this:

Ground (0 x 0.00g) $0.31
Second Day (0 x 0.00g) $0.31
Next Day (0 x 0.00g) $0.31
($0.31 is the handling fee i've set up in admin, so the module found no product and its weight in shopping cart)

(I've configured the products_weight and the figures in shipping table properly, or it's what I thought, at least)
Zones rates module seem to have the same problem.

Any ideas to solve this? pls help. My zen cart version is 1.3.0.1
Thanks you in advance

I supposed my previous post didn't appear on support forum.
So, I make a reply to my own post hoping that it would solve the problem and a person with the answer will see my thread.

Thanks.
