Dynamically check radio buttons

[Padrill]

<input name="rqradioGender" type="radio" value="Male"> Male
<input name="rqradioGender" type="radio" value="Female"> Female


How can I dynamically check a radio button according to a variable's value when in order for radio buttons to work exclusively they have to have the same name?

rqradioGender.value = value doesn't seem to work

Note: rqradioGender.checked = true; always checks 'Female'.

Thanx

There actually in an array so you can try this:
document.form_name.rqradioGender[0].checked=true
document.form_name.rqradioGender[1].checked=true

Why won't this work?

function GILLIGAN(){
if(document.form.radiobuttonname1[0].checked == true){
document.form.radiobuttonname2[0].checked = true;
}
}

It keeps saying Object expected

I'm calling it with an Onclick="GILLIGAN();" on a radio button in the form

There are multiple radio buttons with the same name, but diferent values in both the radiobuttonname1 and radiobuttonname2 areas

Any help is appreciated.

Nevermind, ended up using a different way to do it.
