Hi, Nicolas!
You and your answers are amazing! With your kind help, I managed to get #2, 3, and 4 taken care of! Honestly, I was quite surprised that I could do that!
Regarding #1, the menu background color changed fine, but for some reason, the module background color has not changed, even though I'm pretty sure I have changed it correctly as directed. It shows up as changed in the back-end and shows the color I entered in the Parameters for DIV area. I have tried and saved several times, but maybe I am doing something wrong.
Sorry, but I have a couple of other questions.
Is it possible to default the country in the registration area to the US?
And, is it possible to add a line space in the cart between the address information - the shipping method - and the payment method?
Once again, I thank you.
