WHY isn't this FUCKING WORKING!
I feel your pain.
Here are some tips to help you along your way.
General
Selector vs. Declaration
One important thing to understand is the names for each part of CSS. In the stylesheet, there is the Selector and the Declaration. Understand the differences between these and use these names when asking questions, troubleshooting, emailing etc about your CSS. It will make things easier for all of us.
The Selector is named so because it "selects" the style in your HTML and applies the Declarations to it's content.
The Delcaration is named so because it "declares" that this selector has this power (the CSS styles) to change content.

SJH Physician Directory Submit buttons
If you're having trouble with the SJH green physician directory submit buttons and their background color/gradient, use this CSS:

a.searchbtn span.link
background: #006C64;
background: -webkit-gradient(linear, left top, left bottom, from(#008680), to(#006C64));
background: -moz-linear-gradient(top, #008680, #006C64);
