search button styling

Hi, i am using geodirectory with the advanced search plugin.

I want to highlight the primary searchbutton while the secondary advanced search button should remain grey as per default.

I tried the below CSS but now both buttons turned orange.
see here: https://www.evernote.com/l/AKWEKgCVAdVJPI7cyg-yM-osKAoAhmkm1e0

body .geodir-listing-search.gd-search-bar-style .geodir-loc-bar .clearfix.geodir-loc-bar-in .geodir-search button {
color: #ffffff!important;
background-color: #F68423!important;
border: 1px solid #443a2d!important;
border-radius: 1px!important;
}

Can you help me find the right code?

Thanks in advance! Gerald
