if (document.SubmitRegistration.intOption[i1].checked==true)

What this line do in my code?
if (document.SubmitRegistration.intOption[i1].checked==true)  

Right now i have two option.
Fellows, Affiliates or Correspondents of an actuarial organization or CFA members   100.00*
 
Associates of an actuarial organization   $525*
Please see on that page:
http://209.217.127.200/jp/registration_13_e_.cfm 

If i take out this line 'Associates of an actuarial organization   $525* ' my form calculations will not work... See i took that line (Associates of an actuarial organization   $525*  
) on that page and is not working.
