This seems to be working
function hikashopHandleCases(obj){
   if(obj.name=='data[order][user_choice]'){
    var hide = new Array();
    var show = new Array();
     if(obj.id=='user_choice_activate_both'){
      show.push('numberchoice')
       hide.push('customtext_173_13_32_23');
       hide.push('accountname');
       hide.push('billingaddress');
       hide.push('phone_number');
       hide.push('carrier');
       hide.push('account_number');
       hide.push('pin');
       hide.push('ssn');
       hide.push('esnnumber');
       hide.push('mobile_serial_lock_code');
       hide.push('iqaccount');
     }else if(obj.id=='user_choice_activate_plan_other_phone'){
       show.push('numberchoice')
       hide.push('customtext_173_13_32_23');
       hide.push('accountname');
       hide.push('billingaddress');
       hide.push('phone_number');
       hide.push('carrier');
       hide.push('account_number');
       hide.push('pin');
       hide.push('ssn');
       show.push('esnnumber');
       show.push('mobile_serial_lock_code');
       hide.push('iqaccount');
     }else if(obj.id=='user_choice_activate_plan_iq_phone'){
       hide.push('numberchoice')
       hide.push('customtext_173_13_32_23');
       hide.push('accountname');
       hide.push('billingaddress');
       hide.push('phone_number');
       hide.push('carrier');
       hide.push('account_number');
       hide.push('pin');
       hide.push('ssn');
       hide.push('esnnumber');
       hide.push('mobile_serial_lock_code');
       show.push('iqaccount');
     }
     else if(obj.id=='user_choice_activate_phone'){
       hide.push('numberchoice')
       hide.push('customtext_173_13_32_23');
       hide.push('accountname');
       hide.push('billingaddress');
       hide.push('phone_number');
       hide.push('carrier');
       hide.push('account_number');
       hide.push('pin');
       hide.push('ssn');
       hide.push('esnnumber');
       hide.push('mobile_serial_lock_code');
       show.push('iqaccount');
     }
     
     }
     
switchFields(show,hide);
   
}
what i am trying to do is when they select that they want to keep their number i want them to see these fields
   show.push('customtext_173_13_32_23'); 
       show.push('accountname'); 
       show.push('billingaddress'); 
       show.push('phone_number'); 
       show.push('carrier'); 
       show.push('account_number'); 
       show.push('pin'); 
       show.push('ssn'); the other fields that are currently being viewed from the selection would also show. this part of this project is killing the deadline... hopefully it's something simple..
