Revolution Church Theme HELP! How to make the text in nav bar to uppercase?

Hi

Find this style.css (line 247)

#nav li a, #nav li a:link, #nav li a:visited {
color:#FFFFFF;
display:block;
font-family:Georgia,Times New Roman;
font-size:16px;
font-weight:normal;
margin:0;
padding:9px 15px 8px;
}

add this line within that block
text-transform:uppercase;

Ok how about if i want it both upper case and lower case??

text-transform: capitalize;
