I have a site http://betabookhotels.com, as you cn see there are two forms on the right sidebar.

I need the first one to look like the second one.

The first one has this code: <script type='text/javascript' src='http://www.hotelscombined.com/SearchBox/142080'></script> which has been generated by combined hotels.com. They have told me I can use my own css style so I have tryed placing the follwing styles in my custom css section but nothing has changed:

Code:
#SB_61dbd217e3 label { font-family: "Open Sans", "Helvetica Neue", Helvetica, Arial, sans-serif; color: #BBB; font-weight: 900; text-transform: uppercase; }

#SB_2bcead2309 { border-radius: 0px; -webkit-border-radius: 0px; }
Can anyone help me with what I'm doing wrong or what needs to be done for me to get this form the same as the second?

Much appreciated!
