Please help me on this.

I'm working on a dynamic web survey for someone and I have Javascript that checks radio buttons and disables them when they need to be or checks them out because the script determines where you need to go after submitting on some of the pages. It works fine on Internet Explorer, but it doesn't work with Netscape. I know I need to do some sort of cross-browser compatiblity, but how do I alter this code so it can work with Netscape?

Here's some sample code:

function checkSurvey()
{
thisForm = document.SurveySelect;
if( SurveySelect.parCheck.value == 'N' ) SurveySelect.Survey[0].disabled = true;
if( SurveySelect.stuCheck.value == 'N' ) SurveySelect.Survey[1].disabled = true;
if( SurveySelect.TeaCheck.value == 'N' ) SurveySelect.Survey[2].disabled = true;
if( SurveySelect.BDrCheck.value == 'N' ) SurveySelect.Survey[3].disabled = true;
return true;
}

I would appreciate any help you can give me on this!
