I deleted the code of REGISTER NOW ! button

I deleted the code of REGISTER NOW ! button and now i see only the word. Can you tell me how to correct it?

thank you

Html code you put inside custom HTML module is

main thing about that is class="register_button"

Thank you very much. Now the problem is that green button is always on top o other modules.
How can i make it right?

It's not , look the code in template_css.css:

a.register_button {
float: right;
height: 60px;
width: 190px;
margin: 0 30px 0 0;
-moz-border-radius: 10px 10px 0 0;
-webkit-border-radius: 10px 10px 0 0;
border-radius: 10px 10px 0 0;
text-align: center;
display: block;
line-height: 56px;
color: #fff !important;
font-family: 'PT Sans Narrow', sans-serif;
font-size: 18px;
text-transform: uppercase;
text-decoration: none;
}

only rule it that floats right:

float: right;

Yes but as you see in the photo the green button is above scroller module.
