Well.. i had already found this problem, but had found also a walkaround...
The thing was that the totals had diferente cost in one place and in another..., after asking here in th forum, i decided to disable the shipping cost, and changed the taxes type from % to $, and used that tax as a shipping cost.
Well.. after all this, now I need to be able to have items with free shipping ,but as i said, i was using a tax as shipping cost... so..., i had to turn shipping on again, and had to use the taxes in its primary function... but I still have the problem!
I know my English is no too good... so i'm sending you two images, it sais more than 1000 words...
Hope you could find the problem.
Greetings!!
