i know the coding is really long(sorry) but bear with me. if u noticed theres a NOTICE THIS LINE, BEGIN DIV and END DIV these divs i want to hide it first unless the radio button at NOTICE THIS LINE is clicked yes meaning that if clicked yes the input fields in the divs,as mention, will be shown.

i found this :

$(function(){
    $("#spouse-yes, #spouse-no").change(function(){
        $("#field1, #field2").val("").attr("readonly",true);
        if($("#spouse-yes").is(":checked")){
            $("#field1").removeAttr("readonly");
            $("#field1").focus();
        }
        else if($("#spouse-no").is(":checked")){
            $("#field2").removeAttr("readonly");
            $("#field2").focus();   
        }
    });
});

but it only enables/disables the input fields. i would like my div to be hidden first only then user can fill up the input fields.

JQuery has .hide() and .show() methods you can use to hide and show content.

If you want the digs to be hidden when the page loads, use CSS and set their display: none. Then use the .show() method to unhindered the div(s).

ah.. right. totally forgot about that. shows how much my js knowledge sucks. thanks jorgeM!
