We are running smit 3.88 on dnn 04.09.04 I have shipping set by zip code. If a user tries to check out without selecting a dropdown for shipping it will display an error saying to select a shipping amount. However, if a user selects the shipping method, but does not click calculate shipping, then they can click checkout and not have to pay any shipping. This is only in DNN 4 versions. Do you have a fix for this?

I was afraid you would say that. I'm sure you know as well as I do that upgrading from 4 to 5 is not exactly the easiest thing in the world. Plus, we have multiple modules installed on this, and I'm afraid they might not work with the newer version of dnn. I'll see if I can throw in some client side JS to resolve the issue.
