what is the best way to set focus and select a radio button from groups of 
radio buttons on a form, that both netscape and IE will recognize,
The following works in Netscape but not Explorer,

document.forms[1].elements[rbname][rbindex].focus();
document.forms[1].elements[rbname][rbindex].select();
rbname is the name of the radio button group
rbindex is the index number i want to select of the group

any suggestions would be appreciated

Thank you
