You will see that some links are underlined, others arent. I thought I coded it to underline on hover.
Here is the CSS

A
    {
    margin:0;
    text-decoration:none;
    font: 8.5pt Helvetica, Sans-Serif;
    }
A:link
    {
    background-color:inherit;
    text-decoration:none;
    color:#7b9a39;
    }
A:visited
    {
    background-color:inherit;
    text-decoration:none;
    color:#7b9a39;
    }
A:hover
    {
    background-color:inherit;
    text-decoration:underline;
    color:#7b9a39;
    }
A:active
    {
    background-color:inherit;
    color:#7b9a39;
    }

Thank you for any help in advance.

Here are a few things you can try.

First try replacing your CSS with this one:

a
{
margin:0;
text-decoration:none;
font: 8.5pt Helvetica, Sans-Serif;
}

a:link, a:visited, a:active
{
background-color:inherit;
text-decoration:none;
color:#7b9a39;
}

a:hover
{
background-color:inherit;
text-decoration:underline;
color:#7b9a39;
}

Then, I noticed some of your links have the id #testimonials which has text-decoration: underline associated with it. That is probably your problem. Remove that and you should be good.

#testimonials
{
text-decoration: underline;
margin-bottom: 50px;
}

Ah yes, you're right!

Thanksss

No problems.

You should download the web developer plug-in for FireFox (if you use firefox that is) There is a View CSS option that allows you to quickly hover over elements on a page and see what css classes and id's are assocaited with it.

The plug-in can be found here:

thanks buddy

Also don't capitalize the a. That does make a difference.

and your header should be gif or 8-bit png - it's way too weighty as a jpeg and won't look as good
