On https://www.segufix.com/CSSSculptor/2ColumnFixedLeftSidebarHeaderandFooter_SEGUFIX2012_css/screen.css line 590 you have:
.searchText a:link {
display: block;
text-decoration: none;
border-style: none;
}
Block level elements automatically show on their own line. So the <a> tag above it is what is showing on its own line. Change it to inline-block and that will probably do the trick.
