e-Newsletter – Changes Widget CSS and Formatting

I’m working on getting this up and running. The site is http://www.scubaozzydiving.com and the newsletter signup is on the side-bar at the bottom.

As you can see in the attached jpg, the fields are not formatted well, showing up on the same line and not separate lines. Also, after you subscribe, that white box shows up and it says “You are subscribed successfully!” in white text, which blends into the white box it’s within.

I searched all of the plugin files, the .css file, and even did several searches with dreamweaver for snippets of code that I found in the source and couldn’t find where to make these design changes at.

Sorry for so many questions about this one, but it’s pretty ugly as it is and I’d like to get it looking much nicer.
