Customizing the newsletter form in Prestige Theme

We are trying to customize our newsletter form to include also Name and Country and not only e-mail but we don´t know how to do it. We found some guidance on the internet which made us change the code but now we have by mistake even added something in the code that shouldn´t be there because our footer suddenly looks very strange. This is only a problem when using safari, not chrome which is also very strange.

Thank you for your help!

A simple text field for Country would be like the following:


    
    

Though you’d probably want this to be a dropdown list of all relevant countries.
